Abstract Title: Automation at the CERN SPS and LHC accelerators. Good or bad for operator skills? Speaker Name: Guy Crockford Email: guy.crockford@cern.ch Session: Automation Abstract Type: talk Abstract: The past 20 years have seen great advances in the CERN accelerator control systems. Low level operation skills have been largely replaced by sophisticated sequencers and feedback loops. At the same time, a drive for greater efficiency, a tendency for more complex accelerator operations and a need to reduce the risk of "human error" have rendered these tools essential. The effect of this controls evolution on operator skills will be analysed in the context of SPS and LHC accelerator operations at CERN. |
Abstract Title: Decommissioning the Proton Hall Speaker Name: Angela Hoiem Email: angela@triumf.ca Session: Recommissioning or Decommissioning Abstract Type: talk Abstract: TRIUMF's Proton Hall served the scientific community for many years as a home to experiments such as Parity and TISOL. The Proton Hall was permanently decommissioned this year and construction is currently underway to turn it into the Electron Hall. It will contain a 50MeV E-linac and proton beamline which will deliver beam to the new ARIEL (Advanced Rare Isotope Laboratory) facility. The decommissioning process involved completely clearing the area of all experimental equipment such as spectrometers, magnets, beamlines, beam dumps, shielding and all the associated services. This talk will go over a few of the problems we encountered during decommissioning and the solutions we came up with. |
Abstract Title: Tested by Fire – How two recent Wildfires affected Accelerator Operations at LANL Speaker Name: Thomas Spickermann Email: spickermann@lanl.gov Session: When Disaster Strikes Abstract Type: talk Abstract: The US Southwest experiences numerous wildfires every year, but when a Laboratory engaged in nuclear research is involved it is sure to make world news. Such was the case for Los Alamos National Laboratory (LANL) with the Cerro Grande fire in 2000 and the Las Conchas fire in 2011. Both incidents required the evacuation of Los Alamos and the shutdown of most of LANL operations. LANL includes two large accelerator facilities, the Los Alamos Neutron Science Center (LANSCE), and the Dual Axis Radiographic Hydrodynamic Test Facility (DARHT). LANSCE hosts an 800 MeV proton accelerator that simultaneously provides beams for isotope production, proton radiography and three neutron sources that span a wide range of neutron energies. DARHT consists of two electron induction accelerators at right angles to one another, whose beams are converted to X-rays, which provide multiple-view radiographic images of implosions. In this presentation I will recount the two events, talk about the impacts on LANSCE and DARHT, how accelerator operations personnel and others dealt with the emergencies, and what lessons we learned. |
Abstract Title: From US Navy Mate to Division Leader for Accelerator Operations – Requirements, Development and Care Speaker Name: Thomas Spickermann Email: spickermann@lanl.gov Session: Operator Development Abstract Type: talk Abstract: At the heart of the Los Alamos Neutron Science Center, part of Los Alamos National Laboratory in New Mexico, lies an 800 MeV proton machine, capable of producing up to one MW of proton beam power. Users include the Isotope Production Facility, Proton Radiography, Ultra Cold Neutrons, the Lujan Neutron Scattering Center and Weapons Neutron Research. Protons and H- ions are simultaneously accelerated and delivered to up to four facilities at a time. Each user facility has its own unique and often changing requirements regarding beam energy, intensity, pulse structure, etc. LANSCE accelerator operators are trained to tune the accelerator, the Proton Storage Ring and all beam lines to meet the needs of each user while keeping beam spills at acceptable levels. Emphasis on Formality of Operations is strong at LANSCE, mostly due to the fact that LANL is overseen by NNSA. Operators need to be familiar with almost 200 sections of the LANSCE Accelerator Operations Manual. I will explain how this somewhat unique mix of skills impacts operator’s career paths, starting with the hiring process through qualification and training, both in the control room and in the field, as well as continued education. I will also talk about how staffing levels and a 24/7 shift schedule affect an operator’s ability to pursue a career beyond the control room. Finally, I will contemplate how the future of LANSCE might affect education requirements. |
Abstract Title: Standards-Based Operation of a Nuclear Physics User Facility Speaker Name: Andreas Stolz Email: stolz@nscl.msu.edu Session: Poster Session Abstract Type: poster Abstract: The National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University established management systems for quality, environmental impacts, and occupational health and safety. These systems have been certified according to the international standards ISO 9001, ISO 14001, and ISO 18001 and cover all processes in support of delivery of beams to experimenters. Applying the experience of established industry standards in management of a nuclear physics research facility resulted in efficient, reliable, and safe facility operation and highly satisfied facility users. |
Abstract Title: How J-PARC recovered from the big earth quake Speaker Name: Fujio Naito Email: fujio.naito@kek.jp Session: When Disaster Strikes Abstract Type: talk Abstract: The J-PARC has resumed the beam supply to the experiments from December 2011. The main damages of the facilities by the Great East Japan Earthquake, which happened in the morning of March 11 2011, were almost fixed. Although the operation of the accelerators is frequently interrupted by troubles caused by the damage of the earthquake, the beam intensity for users is the same level as that before the earthquake. The real status of the accelerators after the earth quake will be reported. |
Abstract Title: Operator Development - Nature & Nurture Speaker Name: Isadoro Carlino Email: carlino@jlab.org Session: Operator Development Abstract Type: talk Abstract: Accelerator operators are the human capital that make accelerators run.The preservation of this human capital, both inside the accelerator operations group and outside in the larger organization is a function of both the kinds of staff which are hired and the professional environment in which they are allowed to either flourish or languish. Jefferson Lab has taken a balanced approach to the problems inherent to the unique lifestyle and career path which support of 24/7 accelerator operation entails in its staff. This paper will show how Jefferson Lab has achieved this balance and present concepts that might be useful to other facilities. |
Abstract Title: Coping with the Power Company Speaker Name: Paul Sampson Email: sampson@bnl.gov Session: When Disaster Strikes Abstract Type: talk Abstract: The CAD complex at Brookhaven National Laboratory, which includes the Relativistic Heavy Ion Collider (RHIC), receives power for all systems from the local power company, the Long Island Power Authority (LIPA) via several dedicated high voltage lines. Under certain circumstances, the utility will have need to secure one of more of these lines with little or no notice. During these outages, Accelerator Operations is impacted in much the same way as major failure. This paper will relate recent experiences at BNL and discuss methods for dealing with emergency and otherwise unscheduled electrical outages. Tools and techniques in communication and for scheduling, preparation, outage utilization, recovery and program restoration will be discussed. Possible schemes for reducing dependance on single feeds will be addressed in the summary |

Abstract Title: TRIUMF Electronic Log Book System: Broadcasting Activities Beyond the Control Room Speaker Name: Eric Lee Email: eclee@triumf.ca Session: Communication Abstract Type: talk Abstract: An overview of the web-based electronic log book system in use at the TRIUMF facility for documenting operation activities and system status. This presentation will go over the motivation, structure, and features of the electronic log book system used at the ISAC facility at TRIUMF for keeping operations crew, supporting technicians, management, and users informed of the day-to-day details. |
Abstract Title: Modeling SNS Availability Using BlockSim 7 Speaker Name: Geoffrey Milanovich Email: milanovichgw@ornl.gov Session: Reliability and Availability Abstract Type: talk Abstract: Reliable operation has surpassed luminosity and energy reach as the most important metric in all but a handful of accelerators. Several software tools exist to predict component reliability, test spares policies, and determine cost effective upgrades. SNS has implemented the entire accelerator in ReliaSoft's BlockSim 7, a reliability block diagram and fault tree analysis program. We will share overall availability data for SNS, demonstrate how difficult it is to achieve 95% uptime in such a large system, and show how simulations have affected the klystron spares policy. ORNL/SNS is managed by UT-Battelle, LLC, for the U.S. Department of Energy under contract DE-AC05-00OR22725. |
Abstract Title: Machine Protection: A dominant issue in the LHC operation Speaker Name: Rossano Giachino Email: rossano.giachino@cern.ch Session: Killer Beams Abstract Type: talk Abstract: With the LHC start up we had to learn how to operate powerful beams. The amount energy stored in LHC magnets and beams, and the potential damages produced by uncontrolled loss of this energy lead to the design of a very sophisticated interlock system. In addition the LHC is commissioned in steps of intensity and energy. Each step in energy and/or intensity has to be approved by the Machine protection committee following a strict list of requirements and validation tests. The operation team has learned how to fulfill these vital tests before the nominal beams will collide at high energy. Sequencer, Safe machine parameters, Post-mortem, Collimators, Injection protection, Injection Quality Control, are the Software and Hardware tools that allow us to inject, ramp, squeeze and finally collide beams at 4 TeV. An overview of this special operation dominated by Machine Protection issues will be presented. |
Abstract Title: Benefits of Beam Development Shifts Speaker Name: Eric Chapman Email: echapman@triumf.ca Session: Killer Beams Abstract Type: talk Abstract: Over time standardized tuning procedures have been informally agreed upon in TRIUMF's 520MeV Cyclotron Operations group. However as accelerated beam currents have been increasing, the need for new adaptive tuning techniques have become evident. Despite our facilities lower operating currents than others, damage can still occur to instrumentation or unnecessary radiation hazards can be created by errant accelerated beam. Operations spends the most time tuning our cyclotron and are quite good at “tuning on the fly” but at TRIUMF we have a group of beam physicists that are sometimes quite helpful to operations. This is where development shift planning comes into play. New tuning techniques are tested or more often than not problems in the machine are found. These shifts between beam physicists and Operations play a critical role in the long term stability of Cyclotron beam delivery. |
Abstract Title: How TSL has scaled down and streamlined Speaker Name: Mikael Pettersson Email: mikael.pettersson@tsl.uu.se Session: Poster Session Abstract Type: poster Abstract: TSL has gone through reorientation from mainly Physics to Therapy and Commercial irradiation. This meant decreased staff size so most of the fulltime operators were replaced with part time operators, new control programs, new quality routines, remote login and alarms. The beam time had to be better utilised so user controlled beam sharing were introduced. Less usage of energy saves money so TSL are putting the machine to sleep mode during nights and still have stable beam to deliver every morning. |
Abstract Title: Web service data interface to accelerator control signal data Speaker Name: Wan Tianmin Email: wantianmin@sinap.ac.cn Session: Communication Abstract Type: poster Abstract: During the running of accelerator, a large amount of signal was archived and monitored. People outside the control network may interested in different arts of the signal data, but our accelerator signal is transport on network by EPICS CA(Experimental Physics and Industrial Control System Channel Access) rotocol,one needs to install and configure some EPICS CA client to access these signal. In some case, this seems to be difficult and tedious. In our applications, a web server is configured to provide these signal, all of the data is provided in JSON (JavaScript Object Notation) format. one can use web browser or something else to fetch these data, further more, in order to improve the performance of the data interface, a memory database has been set up and configured as a middle layer between the web server and EPICS CA server. The data interface shows good performance and great convenient in test and practice use. |
Abstract Title: Information And Communication In Operation At GSI Speaker Name: Uwe Scheeler Email: u.scheeler@gsi.de Session: Communication Abstract Type: talk Abstract: Exchange and distribution of information is a key component in accelerator operation. The main control room is the central location where both the machine operation status and the information regarding organizational processes are available. In all situations the shift crew has to gather that information, to evaluate and to distribute it afterwards. Using of telephone, intercom and pager systems supports it. In Order to enable communication, access to the GSI main control room is not restricted. On the other hand, you need to limit the number of visitors. Publishing details about the present operation status in the intranet and meetings in regular intervals facilitate that task. You will find that there are different kinds of information and it is not necessary to provide all information to everybody. And there is a difference between oral and written communication. The talk shows how the operation crew at GSI faces the challenges in this field. |
Abstract Title: Promethean Exchange: Bringing Expert Tools & Diagnostic Experience to Operations Speaker Name: Michael McCaughan Email: michaelm@jlab.org Session: Diagnostics Abstract Type: talk Abstract: Operators need a variety of diagnostic tools in order to make their lives easier. Sometimes it becomes necessary to add or improve the suite of diagnostics in order to do new or different jobs, or to improve upon existing methods in one's accelerator. This talk will attempt to outline various methods by which specific diagnostic improvements have been achieved in the CEBAF accelerator at Jefferson lab and abstract methods of process which can be applied to any lab/setting. |
Abstract Title: Overview of the Magnet Activities at HIT Speaker Name: Rainer Cee Email: rainer.cee@med-uni-heidelberg.de Session: Poster Session Abstract Type: poster Abstract: The Heidelberg Ion Beam Therapy Centre (HIT) is the first facility in Europe with a dedicated heavy ion accelerator for cancer treatment with carbon ions and protons. Today, after three years of regular operation, up to 45 patient irradiations per day can by applied. The accelerator comprises 146 normal conducting magnets ranging from 9 kg LEBT double steerers to the 74 tons 90° dipole on the gantry. Due to its medical application a high reliability is demanded from all subsystems. To reduce unscheduled shut downs due to magnet failures we set up a concept based on an exceptional spares inventory and preventive maintenance which will be presented in this paper. Moreover we will discuss other activities concerning the magnets such as corrective maintenance and copper passivation. |
Abstract Title: Superconductivity in the BEPCII Speaker Name: Qing Qin Email: qinq@ihep.ac.cn Session: Superconductivity Abstract Type: talk Abstract: The Upgrade Project of Beijing Electron Positron Collider, BEPCII, applied superconductivity in RF cavities, final focusing magnets, and detector solenoid since the design stage. A cryogenics system was set up to accommodate these superconducting elements. Though a lot of faults, from cryogenics system, quench system, power supplies to RF system, happened for many times and time-consuming recovered, the beam performance is quite good compared to the original BEPC. The superconducting technology is also developed along with these key elements. Performance of superconducting parts will be reviewed. Main faults and improvements are also discussed. |
Abstract Title: Demolition of the Bevatron Speaker Name: Jim Morel Email: jrmorel@lbl.gov Session: Recommissioning or Decommissioning Abstract Type: talk Abstract: The Bevatron, at the Lawrence Berkeley National Laboratory, was demolished starting in 2008 and finishing in 2012. The Bevatron was the premier particle accelerator for the 1950’s, designed to discover the anti-proton, it succeed at that task and continued on for a long career until it was shutdown 1993. The massive facility sat for another 15 year until the funding was available to move forward with its decommissioning and demolition. I will discuss the decommissioning of the Bevatron and the project to demolish the structure. The demolition project took 3.5 years and cost about $50 million dollars. There were several lessons learned from the project that will be discussed. |
Abstract Title: Experience with Cryogenic Operations During the FermiLab Collider Program Speaker Name: Stanley Johnson Email: srj@fnal.gov Session: Superconductivity Abstract Type: talk Abstract: During the FermiLab collider program cryogenics played a critical role. The Main Control Room operators dealt with various cryogenics systems while running the collider. Tasks included both operating and monitoring the various cryogenic systems. The Control Room also interfaced with a separate cryogenics group that was responsible for maintenance and operation of the central cryogenic plant. Stability of the cryogenic systems was critical to the physics program. This talk will look at some of the lessons learned during that program and how we can apply them moving forward. |
Abstract Title: Operation of the LHC cryogenic system and interface with beam and machine operation. Speaker Name: Serge Claudet Email: serge.claudet@cern.ch Session: Superconductivity Abstract Type: talk Abstract: For some decades, the technology for the high-energy physics research requires superconductivity for the key components of the concerned accelerators. The Large Hadrons Collider (LHC) at CERN,Geneva is made of 24km of superconducting magnets and requires unprecedented cooling capacity below 2K. The presentation will describe the specific constraints and the approach followed towards operation wit high availability of the LHC cryogenic system for physics, with a particular analysis of the interface and potential synergies between the LHC machine operation and cryogenics operation teams. |
Abstract Title: How we managed Cern's most important power cut. Speaker Name: Jesper Nielsen Email: jesper.nielsen@cern.ch Session: When Disaster Strikes Abstract Type: talk Abstract: When disaster strikes many things need to happen quickly both in the central control room and on-site. In July 2006 CERN suffered its most important power cut ever. The main power was lost, the spare did not work, generators failed and UPS systems ran flat. In this talk we will go through that event and look more into what can happen, how the situation is recovered and what we learned from this particular event. A crucial point is how to handle the many alarms, the startup priorities and who should take decisions. We will also look more into how the communication is done at CERN during major incidents, including both what is done now, but also exciting new projects. |
Abstract Title: Moving Cyclotron room from old to new location with no lost time Speaker Name: Jozef Orzechowski Email: joski@triumf.ca Session: Recommissioning or Decommissioning Abstract Type: talk Abstract: The original operation dates back to 1983 when the first commercial cyclotron (CP42) was installed. At that time all activities were limited to one cyclotron and the control room was in the “right” location. Years later, in 1990, the second commercial cyclotron was added and the existing control room was filled up to its capacity. Making things even worse, this tiny control room was the main access to the second cyclotron (TR30-1) and consequently it had to serve as a hallway as well. Traffic through this room was a big distraction for the operators. On top of that, this room was poorly ventilated and located in the evacuation zone, so in case of evacuation due to ventilation failure it had to be evacuated. In 2000 the idea of adding a third cyclotron was coming to light. If this were to happen a new control room would be needed as the present control room was filled to capacity. |
Abstract Title: RIKEN Nishina Center’s Response to Fukushima Daiichi Nuclear Disaster Speaker Name: Tadashi Fujinawa Email: fujinawa@riken.jp Session: When Disaster Strikes Abstract Type: talk Abstract: The large earthquake struck East Japan with a magnitude 9.0 on March 11 2011. All of the transition lines connecting Tokyo electric power cooperation (TEPCO)’s Fukushima Daiichi Nuclear power station were brought down by the earthquake. 30 minutes later, the tsunami reached the power station and the emergency diesel generators were submerged and no power was generated. The three units of the reactor melted-down and three reactor houses had hydrogen explosion. Four units were heavily damaged out of six total units in Fukushima Daiichi. “Daiichi” means “number one” and there is No.2 in Fukushima prefecture as well. As requested by the Ministry of Education, Culture, Sports, Science and Technology (MEXT), the RIKEN Nishina Center (RNC), as a member of the Nuclear Experimental Forum composed of 31 institutes, universities and individual, have contributed in the radiation screening effort by providing human resources, instruments, and transportation vehicles to the medical teams of Fukushima’s prefectural government (FPG). This activity was done until early August 2011. RNC was the top contributor in the Nuclear Experimental Forum with 28.3% of the total 361 person-days. I personally visited three times for a total of 16 days. RNC also carried out extraction work and sample tests of soil contamination which requested by MEXT. The monitoring data of RNC is reported to the Wako city office and it is open to the public. Last summer, RIKEN was legally required to save 15% (equivalent of 3.3MW )of electricity of the quantity set in its contract .In addition, since RIKEN’s Energy Saving Committee decided to cut down power consumption by 25% almost all the time, it became extremely difficult to conduct experiments using accelerators. Due to many difficulties, the operation of accelerators was cut down to a minimum during the first half of the year. However, with the start of the RIBF experiments in early October, the power consumption increased in Autumn. RNC has a gas-turbine based co-generation system (CGS) with an electrical capacity of 6.5 MW.CGS which operated non-stop until the end of the year. RIKEN is constructing two sets of CGS whose capacities is each 1.5 MW and will be commissioned this Autumn. |
Abstract Title: Tuning an Accelerator for 1 MW Speaker Name: Charles Peters Email: peterscc@ornl.gov Session: Killer Beams Abstract Type: talk Abstract: The Spallation Neutron Source (SNS) is in neutron production for typically two 5-month long runs during the year. During the first week of each run period, the physicists and operators work together to set up the accelerator. After the initial tune up, SNS Accelerator Operations assumes responsibility for beam setup, documentation, and tune maintenance. Beam setup and documentation are done at each ion source change (typically every 5 weeks), and tuning is done to maintain appropriate beam on target parameters and to minimize beam loss. In this talk we will discuss the transition from accelerator physics development to a production machine and the transition of beam loss tuning from physicist to operator within the constraints imposed by a 1 MW beam. |
Abstract Title: Hurricane Isabel's Impact on Jefferson Lab Speaker Name: Yan Wang Email: ywang@jlab.org Session: When Disaster Strikes Abstract Type: talk Abstract: Hurricane Isabel, originally a Category 5 storm (with winds in excess of 155mph), gradually deteriorated as it approached the eastern seashore of the United States arriving at Jefferson Lab on September 18, 2003 with sustained winds of 75mph or a category 2 storm. The storm resulted in minimal direct damage to the infrastructure of Jefferson Lab however caused significant community damage and loss of electric power for four days. Due to the power outage, public travel was limited and JLab was closed for five days before staff was allowed back to work. Without accelerator site utilities beamline vacuum deteriorated and the superconducting cryomodules warmed up causing a total loss of the liquid helium (65,000 liters). This presentation will review the lessons learned and preventive measures that were put in place to mitigate the impact of future hurricanes. |
Abstract Title: Operations of the National Superconducting Cyclotron Laboratory Speaker Name: Andreas Stolz Email: stolz@nscl.msu.edu Session: How We Do Business Abstract Type: talk Abstract: The National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University is a national user facility providing rare isotope beams for nuclear science and societal applications. Accelerated primary beams range from oxygen to uranium with energies of up to 170 MeV/nucleon. NSCL is currently funded for 2500 operations hours and operates 24/7 during beam delivery periods. Experiments with up to a week duration typically require several different beam tunes. NSCL has established an ISO 9001 quality management system for the delivery of rare isotope beams. |
Abstract Title: Introduction to TRIUMF Speaker Name: Eric Chapman Email: echapman@triumf.ca Session: How We Do Business Abstract Type: talk Abstract: With its first accelerated beam in December 1974, TRIUMF's 520MeV. Cyclotron still readily accelerates up to 300uA of H- ions. Running 24hours a day 7 days a week by an immediate operations staff of 15, the Cyclotron uses electron stripping to extract protons down its three primary beamlines. All three being important, one of high scientific interest is the newer ISAC facility. ISAC and its currently under construction expansion ARIEL, allow for the delivery of exotic nuclei to experimenters. Located in Vancouver, Canada, TRIUMF is run by a consortium of Canadian universities receives funding from the Canadian National Research Council. With upgrades to both the Cyclotron and ISAC facilities, TRIUMF plans on continuing to advance scientific discovery for years to come. |
Abstract Title: Operations at the Spallation Neutron Source Speaker Name: Glen Johns Email: johnsgd@ornl.gov Session: How We Do Business Abstract Type: talk Abstract: The Spallation Neutron Source (SNS) located at the Oak Ridge National Laboratory is the world’s most intense pulsed neutron source. At the heart of the facility is a 1 GeV superconducting proton linear accelerator operating with a beam power of 1MW for conducting neutron scattering research. This talk will provide an overview of the accelerator facility, our yearly operating schedule, our shift staffing, and our availability statistics.

Abstract Title: The Skill Management for an accelerator facility by adapting experience of aircraft maintenance. Speaker Name: Hiromi Inokuchi Email: inokuchi@nirs.go.jp Session: Operator Development Abstract Type: talk Abstract: At National Institute of Radiological Sciences in Japan, we have just started to develop skill management system to the HIMAC, Heavy Ion Medical Accelerator in Chiba. The system is based on aircraft maintenance system, which integrates the controlling of the manual, man, machine, and method. There, maintenance tasks are grouped by safety implication and must be carried out by qualified mechanics with appropriate level of skills. Skill of personnel is the crucial element of “man” aspect in aircraft operation and this is also the case with particle accelerator operation. By clarifying the skill level, skill management will provide the useful information regarding job assignment for daily operation among operators of various skill levels, which will enhance the performance of aircraft/accelerator with optimized cost. The skill management also aims to check the skill of individual person and to plan the proper training for each. We have finalized the skill map which is list of all required skill for operation and maintenance of the HIMAC and started to review concerning qualification and approval. We would like to discuss following issues that we are facing: A. How do you maintain the operator skill ? B. How do you give the incentive to the operator ? |
Abstract Title: Spare Parts Inventory at NSCL Speaker Name: Jon Bonofiglio Email: bonofigl@nscl.msu.edu Session: Reliability and Availability Abstract Type: talk Abstract: The National Superconducting Cyclotron Laboratory (NSCL) is a world leader in rare isotope research and nuclear science education. Located on the campus of Michigan State University, NSCL scientists and researchers employ a wide range of tools for conducting advanced research in fundamental nuclear science, nuclear astrophysics, and accelerator physics. A spare parts inventory is critical in ensuring NSCL can meet research needs. As well as having the correct spare parts on-hand, the ability to access them in a timely manner is also important. Custom software, coupled with off-the-shelf hardware allows maintenance staff to quickly find the appropriate part and accurately checking that part out of the system or add a new part into the system. Report generation is another critical component of an inventory system. The ability to generate reports of needed inventory and have vendor information readily available makes reordering and restocking less burdensome. |
Abstract Title: Operational Demands of REA3 at NSCL Speaker Name: Jon Bonofiglio Email: bonofigl@nscl.msu.edu Session: Adapting to Changes Abstract Type: talk Abstract: The National Superconducting Cyclotron Laboratory (NSCL) is a world leader in rare isotope research and nuclear science education. Located on the campus of Michigan State University, NSCL scientists and researchers employ a wide range of tools for conducting advanced research in fundamental nuclear science, nuclear astrophysics, and accelerator physics. One of these tools is ReA3, which will provide a world-unique low energy rare isotope beams produced by stopping fast, separated rare isotopes in a gas-stopper, and then reaccelerating them in a Linear Accelerator. The Coupled Cyclotrons at NSCL are currently operated by a crew of 12 operators. Increased operational hours for ReA3 have meant that additional demands have been placed upon the operator staff. The net effect of these changes meant NSCL would be commissioning and operating a completely different accelerator with no increasing in staffing that would also be needed when ReA3 goes into full production mode. This additional demand for operational resources coupled with the usual staff fluctuations has stretched operator resources tremendously. Adapting to these changes will mean adjustment of the operator schedule, hiring of a replacement operator, additional operator training for ReA3 and additional maintenance tasks associated with maintaining ReA3. |
Abstract Title: Development achieved by SOLEIL operation group and main results of the operation of the installation Speaker Name: Xavier DELETOILLE Email: xavier.deletoille@synchrotron-soleil.fr Session: Poster Session Abstract Type: poster Abstract: SOLEIL, the 3rd generation French synchrotron light source, has progressively increased its activity since its starting up in 2007. In 2011, the total beam time has reached 6512 hours out of which 5328 hours were delivered to the 26 beamlines currently in operation. For the operation of the accelerators, a group of 8 operators under the supervision of two people ensures the presence in the control room 24h/24 and 7 days a week. They are assisted by part-time operators who are mainly coming from the Machine Division. Being at the origin of a large number of GlobalScreen (SCADA) applications, useful to the commissioning, operators go on developing applications oriented operation in Labview, Python, Matlab ... and are responsible for installing and monitoring new equipment (temperature measurement, video monitoring and water leak detection in the tunnels, ...). The group documents all the tracking of machine operations through electronic logbooks which it provides balance-sheet every week, at the end of each Run and year. The poster will present some examples of applications and projects developed by the group and the main results of the operation of the installation. |
Abstract Title: Training Advanced Photon Source Operators: From the Street to the MCR Speaker Name: Joseph Sutton Email: jsutton@aps.anl.gov Session: Operator Development Abstract Type: talk Abstract: Operators at the Advanced Photon Source come from various backgrounds prior to their employment at the APS. Training them to become functioning operators presents challenges that we tackle with a graduated training program. The program consists of milestone testing of both written and operational examinations. While the Training is largely self-paced, it is led by a combination of Chief of Operation and Assistant Chief of Operation instruction. While the system has been effective, it has certain drawbacks. I will be exploring the benefits and drawbacks of our program, while nodding to the future. |
Abstract Title: DESY: From High Energy Physics to Synchrotron Radiation Speaker Name: Michael Bieler Email: bieler@desy.de Session: Adapting to Changes Abstract Type: talk Abstract: From it's foundation in the early 60ties until the shutdown of HERA in 2007 DESY had a long history as a high energy physics lab. Although the focus of the lab was clearly on particle physics, there were from the very beginning some parasitic experiments, which made use of synchrotron radiation. Later the smallest storage ring at DESY, DORIS, was converted into a synchrotron radiation facility, and since the end of the HERA program in 2007, all accelerators at DESY are running for synchrotron radiation exclusively. The influence of these changes on the operations group will be presented. |
Abstract Title: The role of CERN PS complex operation teams in the development of diagnostics applications Speaker Name: Marc Delrieux Email: marc.delrieux@cern.ch Session: Diagnostics Abstract Type: talk Abstract: With more than 50 years of operation, CERN's Proton Synchrotron complex has known numerous generations of controls and diagnostics systems. In this presentation, some of the most recent Beam Instrumentation applications that are used by operations teams on a daily basis will be reviewed. In particular, I will present how operations is involved into the development of these tools in order to ensure that they meet the operational requirements. We will also discuss what actions are or could be taken if they don't completely fulfill expectations. |
Abstract Title: IEC61508 at ISIS Speaker Name: Bob Mannix Email: bob.mannix@stfc.ac.uk Session: Safety and Regulation Abstract Type: talk Abstract: The ISIS Personnel Protection System (PPS) and Beam Protection System(BPS) were upgraded for ISIS two-target operation about five years ago. The decision was taken then to build IEC61508-compliant systems using Functional Safety Analysis. This path was also followed for Target 2 Instrument access controls. We explore our experience and the business case for IEC61508 compliance (an active topic at ISIS). |
Abstract Title: Communication flow at Elettra. Speaker Name: Stefano Krecic Email: stefano.krecic@elettra.trieste.it Session: Communication Abstract Type: talk Abstract: Communication skills are essential in all spheres of life. Customers satisfaction cannot be only measured by machine parameters like uptime or beam quality, in fact it's heavly influenced by the communication between who works to improve machine performance and who uses the beam. Without an effective means to communicate will not be possible to create a timely and accurate information flow between control room and experiments who become isolated from the machine status. The importance of communication is crucial to the success in our business, if the right message does not get to the right person, in the right format, then this could create disatisfaction. In the talk it will be presented how Elettra successfully improved the communication channels with the users. |
Abstract Title: FLASH Operation at DESY Speaker Name: Michael Bieler Email: bieler@desy.de Session: X-Ray FEL Operation Abstract Type: talk Abstract: When DESY started operating FLASH, the Free Electron Laser at Hamburg, most of the operators in the control room had a lot of experience in storage ring operation, but hardly any idea of how to run an FEL. At that time FLASH was more an experimental accelerator than a user facility. Operation of FLASH was focused on machine studies, conducted by scientists and supported by a rather rudimentary control system. This talk describes the transformation of FLASH from an experiment to a user facility. |
Abstract Title: Automation of Operations at Fermilab Speaker Name: Duane Newhart Email: newhart@fnal.gov Session: Automation Abstract Type: talk Abstract: Implementing system automation to increase productivity, improve efficiency, ensure repeatability, and reduce errors has become essential for complex accelerator operations. This presentation will address some of the positive and negative effects of automation on operations and operators using experiences and examples from the Fermilab Operations Department. |
Abstract Title: LCLS Availability at SLAC Speaker Name: William Colocho Email: colocho@slac.stanford.edu Session: Reliability and Availability Abstract Type: poster Abstract: The Linac Coherent Light Source Free Electron Laser facility at SLAC National Laboratory is in the middle of its 6th user run. Typically two user experiments are performed in a 5 day block of time. This poster will share availability and reliability data for LCLS. The poster will include MTBF/MTTR tables as well as subsystem availability budget tables and subsystems' reliability performance. A short description of work underway to improve critical systems' reliability will be included. |
Abstract Title: Operator vs Automation, can a balance be achieved? Speaker Name: Navid Radnia Email: NSRadnia@lbl.gov Session: Automation Abstract Type: talk Abstract: This is an overview of attempts to bring automated control systems to the 88-Inch Cyclotron over its 52 years of operation. A system was proposed and implemented in 1965, with poor results. As technology improved, proposals were made and met resistance due to budget limitations and operations reluctance to shift toward automation. Future advancements will depend greatly on finding a workable balance between operations and automation. Machine efficiency, operator knowledge, creativity and problem solving ability, and quality assurance must all be considered as automation is proposed and implemented. |
Abstract Title: BNL Collider-Accelerator Automation Impact on Operations Speaker Name: Christopher Zimmer Email: czimmer@bnl.gov Session: Automation Abstract Type: talk Abstract: The ever-increasing complexity of accelerator and collider operations at Brookhaven National Laboratory has necessitated a heavy reliance on automated execution of procedures. Automation not only promotes efficiency, but helps to mitigate equipment damage and improper execution of tasks that may lead to significant downtime. Conversely, some operators have transitioned to a more basic role as a button-pusher. This generally decreasing level of operator involvement fosters a fundamental lack of comprehension with regard to accelerator operation/tuning/reconfiguration and may actually increase the probability of a mistake. Furthermore, while relatively new and sophisticated tune/orbit feedback loops present similar issues of lessened operator involvement, the detailed workings of these systems are only fully understood by the system expert(s) and thus present a single point of failure with errors that are often abstruse. Adequacy of automation in comparison to overkill will be discussed, as will the need for effective dispersion of knowledge and continuing education of operators in order for operational expertise to be achieved and maintained. |
Abstract Title: Operation management of S3HC (superconducting RF cavity) at Elettra Speaker Name: Pietro Zupancich Email: pietro.zupancich@elettra.trieste.it Session: Superconductivity Abstract Type: poster Abstract: Elettra is a third generation synchrotron light sources, located in Trieste, Italy. A superconducting third harmonic cavity was installed in 2002 in the storage ring in order to lengthen bunches and improve Touschek lifetime. This has implied a change in the operation, enlarging the operators knowledge in the superconducting environments. Even if a cryogenics specialized group has not be formed just for a single RF cryogenic plant, the operators are going to completely manage the plant. Their training has been taking place on the field participating in the recovery operations and maintenance besides common operations. Some routine operations and extraordinary interventions carried on during the last ten years will be presented in this poster. |
Abstract Title: Electronic Logbooking at SLAC Speaker Name: Matthew Gibbs Email: mgibbs@slac.stanford.edu Session: Communication Abstract Type: talk Abstract: In use since 2005, the electronic logbook at SLAC has grown to support nine different groups, including accelerator operations for several different accelerators (The PEP-II B-Factory, LCLS, FACET, SPEAR, and NLCTA) and many maintenance departments. A brief overview of the logbook's architecture and operation will be given, followed by an in-depth investigation of the logbook interface and how it facilitates (or in some cases, hinders) fast, efficient, and expressive event logging and inter-group communication. Several novel features of the logbook will be presented, including a system to automatically classify logbook entries based on their content, and an iOS mobile application. Finally, there will be a discussion of the lessons learned from seven years of use, and how they can be applied to create a better design for a future logbook. |
Abstract Title: Installation of compact injector at HIMAC Speaker Name: TOSHINOBU SASANO Email: aec2g@nirs.go.jp Session: Poster Session Abstract Type: poster Abstract: The compact injector system was installed to the injector area of HIMAC, Heavy Ion Medical Accelerator in Chiba, during 2007-2011 periods. The purpose is to backup the existing injector system, which is almost 20 years old now. The compact injector system is a product of R&D activity at NIRS, National Institute of Radiological Sciences, in preceding years. It consists of an Electron Cyclotron Resonance Ion Source (ECRIS), a Radio Frequency Quadrupole (RFQ) Linac and an Alternating-Phase-Focusing (APF) Interdigital H-mode Drift-Tube-Linac (IH-DTL). Stand alone Beam test was done in 2006 with satisfactory performance, which leads to adaptation of the design to Gunma facility. Installation to the running facility presented issues in many ways. For the hardware, we have to fit into the spare area of the existing injector room. We had to build a platform and house ECRIS in vertical way, as well as place the RF amplifiers on the upper deck. For the software issue, device control and interlock logic must be reviewed and modified to conform with existing system. Beam commissioning of the compact injector in the HIMAC facility was made since 2011, and carbon beam from the injector were accelerated injected to the HIMAC synchrotrons, and accelerated up to 400MeV/u. As result of the beam test, we observed sufficient beam intensity, as required by medical treatment. In this paper, we will describe on developments for the installation, as well as the results of the beam tests in the HIMAC. |
Abstract Title: Diagnostic tool development by Operations group Speaker Name: Yi Chih Liu Email: yichihl@nsrrc.org.tw Session: Diagnostics Abstract Type: talk Abstract: This talk gives an overview about the progress of diagnostic tools developed by OP group; those could monitor both the linac performance and the booster performance, and monitor the jitter of kickers every injection shot. It also discusses the failure analysis using postmodern diagnostics developed by other groups, and uses the analysis result to help operator communicate with other groups. |
Abstract Title: The New Alarm Display for the RHIC Control Room Speaker Name: Peter Ingrassia Email: ingrassia@bnl.gov Session: Communication Abstract Type: talk Abstract: The Alarm Display for the new RHIC Control Room has undergone a radical reworking. While keeping some of the existing software infrastructure the display adds new database driven features to assist operators to track and manage alarms. A key feature of the application facilitates communication from operator to operator and operator to system specialist of the status e.g. "work in progress" of individual alarms. A new summary display, borrowed from KEK, helps operators pinpoint "distressed" accelerators. This talk will summarize the new features of the alarm display and will review operator experience with the application after two years of use. |
Abstract Title: Guaranteeing the Safe Injection of Electrons into the Storage ring with the Master Shutters enabled Speaker Name: Don McGilvery Email: don.mcgilvery@synchrotron.org.au Session: Safety and Regulation Abstract Type: talk Abstract: In May this year the Australian Synchrotron light source changed operational mode from 12 hourly scheduled closed shutter fills (Fill on Fill operation) to short term (~3 min.) periodic top up fills with beam line shutters enabled (Top Up operation). In Top Up operation there is the potential to send high energy (3GeV) electrons down a beam line. This talk presents the process we adopted to ensure safe operation under all possible conditions including the unexpected failure of components or systems. It also discusses the protection systems we installed and the changes to routine operations to provide extended interlocking functionality and reduce the dependence on administrative controls. Finally, a report on the operational improvements in the beam quality delivered to the beam lines will be presented. |
Abstract Title: Recovering CYRIC from the Great East Japan Earthquake Speaker Name: Takashi Wakui Email: wakui@cyric.tohoku.ac.jp Session: Poster Session Abstract Type: poster Abstract: The Great East Japan Earthquake has inflicted damages on the accelerator facility of the Cyclotron and Radioisotope Center (CYRIC), Tohoku University. The K=110 MeV cyclotron was slanted due to the damage of props supporting the cyclotron. The cyclotron building has also been slightly inclined. This situation requires the re-alignment of all beam transport lines and the cyclotron. The earthquake caused also many damages to some components of the cyclotron as well as the beam transport lines. Fortunately, no one was injured at CYRIC. The restoration work was started on July 2011 and will be completed by July 2012. The damages and the current status will be reported. |
Abstract Title: Recommissioning SLAC's West Linac Complex for FACET Speaker Name: Peter Schuh Email: schuh@slac.stanford.edu Session: Recommissioning or Decommissioning Abstract Type: talk Abstract: SLAC National Accelerator Laboratory's Facility for Advanced Accelerator Experimental Tests (FACET) provides electron beams for accelerator research. FACET uses the first 2 km of SLAC's 3 km Linac. This portion of SLAC's accelerator facility was last used in 2008 to provide electron and positron beams for injection into PEP-II. Recommissioning the facility for FACET began in June 2011. Operational challenges included training operators and transitioning to operating multiple accelerator programs simultaneously. Pre-commissioning preparation, current status, and lessons learned will be presented. |
Abstract Title: A simple system to trigger Post Mortem Data Capture on our Beam Position Monitors Speaker Name: Don McGilvery Email: don.mcgilvery@synchrotron.org.au Session: Clever Solutions to Small Problems Abstract Type: talk Abstract: The Australian Synchrotron light source uses 98 Libera Electron BPMs to monitor the position of electrons in the storage ring. These capture history data which can be frozen when provided with a trigger. We wished to capture a beam loss trigger from any of the 28 Orbit Interlock BPMs and send out a synchronous Post Mortem trigger to the 98 BPM boxes. A full engineering solution would use kilometers of cable and a rack full of electronics. As an Operator project we achieved our desired result with a handful of opto-couplers and a single coax cable daisy chained between the sectors. |
Abstract Title: on reducing water-related troubles at HIMAC Speaker Name: Shunsuke Saito Email: aecring@nirs.go.jp Session: Poster Session Abstract Type: poster Abstract: HIMAC, Heavy Ion Medical Accelerator in Chiba, provides carbon ion beam for cancer treatment during daytime of weekdays and for biological and physical research during nights and weekends. Beam down will cause major problem against treatments and research. Our experience indicates that RF, Vacuum, Cooling water system are dominant causes of the down. In the cooling water system, we found that troubles are in two classes: decreased water-flow at a magnet and water leakage. We have introduced two systems as a countermeasure against them. One is a remote monitoring of water-flow at each magnet, which shows and predicts trends of flow and gives warning sounds. We have successfully prevented magnet faults due to water-flow depletion during beam supply. The other is a leakage detection system with floor-wide wiring. The system has been contributing to achieve a significant reduction of downtime by identifying the area where leakage occurs. Details of these systems and resulted improvements in operation status will be reported. |
Abstract Title: Electronic Form for Management of Work on Radiation Safety Configuration Controled Items at SLAC Speaker Name: Zoe Van Hoover Email: zoevh@slac.stanford.edu Session: Safety and Regulation Abstract Type: talk Abstract: SLAC uses Radiation Safety Work Control Forms (RSWCFs) to plan, approve, control, and track work on configuration controlled radiation safety systems. After completion of over 3500 paper RSWCFs over the course of over 20 years, the paper forms used to manage this process have been retired and replaced with a web-based electronic RSWCF. Electronic RSWCFs were rolled out for the SLAC 2-Mile LINAC facility in January 2011, and expanded to apply to SPEAR3 accelerator operations in June 2012. The new electronic RSWCFs are tied to the existing Computer Assisted Trouble Entry and Reporting (CATER) system, providing better integration of Radiation Safety Configuration Control management with other aspects of work planning and control. Electronic RSWCFs also allow remote RSWCF viewing and editing, which improves efficiency and effectiveness of RSWCF management. |
Abstract Title: Tuning Techniques and Operator Diagnostics for FACET at SLAC National Accelerator Laboratory Speaker Name: Christopher Melton Email: cmelton@slac.stanford.edu Session: Diagnostics Abstract Type: talk Abstract: FACET is an R&D facility for advanced beam physics at the SLAC National Accelerator Laboratory, designed to study plasma wakefield acceleration. This facility uses the SLAC linear accelerator with the goal to provide high energy density electron and positron beams with peak currents of 20kA, focused down to a 10x10 micron transverse spot size at an energy of 23 GeV. A key component of the experimental program at FACET is second-generation research in plasma wakefield acceleration, including high-gradient electron acceleration, as well as terahertz, magnetic switching, and other research. During the 2012 FACET experimental run improvements were made toward achieving the design goals, but many challenges were encountered in beam tuning, efficiency, and reproducibility. By exploring discrete regions of longitudinal and transverse beam phase space with specialized tuning techniques and tools, many challenges were resolved. |
Abstract Title: How WAO got started Speaker Name: Ron Lauze Email: lauze@jlab.org Session: How We Do Business Abstract Type: talk Abstract: In the early 90's, Ron Lauze was asked to help form an operations group to run the accelerator being built at Jefferson Lab in Newport News, Virginia. Having no previous operations experience, he decided the best way to proceed was to discuss what does/doesn't work with the operations staff at other labs. After a number of site visits, he began to wonder why operations staff from the various labs didn't meet on a regular basis to discuss the many common issues. This talk will give the attendees a feel for why and how WAO was started, how it has developed over the years, and hopefully some funny stories about things that happened along the way. |
Abstract Title: Regulatory Experience and Developments Related to Accelerator Isotope Production Speaker Name: Abdul Alwani Email: abdul.alwani@cnsc-ccsc.gc.ca Session: Safety and Regulation Abstract Type: talk Abstract: In Canada, the past four years saw a significant increase in interest and projects related to using particle accelerators, such as cyclotrons and high power electron linacs, to produce medical radioisotopes. The Canadian Nuclear Safety Commission, Canada’s nuclear regulator, which regulates all particle accelerator facilities in the country, has been involved in making appropriate changes to the regulatory practices and framework to accommodate such new facilities. Also, the CNSC has assisted other government departments on the policy front related to isotope production. The talk will provide some details about this experience including various challenges. In addition, the CNSC, in general, places an important role for the safety culture in promoting and ensuring safety of its licensed facilities. The safety culture aspects of the regulatory experience related to isotope production accelerator licensing will be reviewed. |
Abstract Title: ISIS - Continued Operations 1984 – 2012 and beyond Speaker Name: Alan Stevens Email: alan.stevens@stfc.ac.uk Session: How We Do Business Abstract Type: talk Abstract: ISIS is one of the world’s most productive pulsed spallation neutron sources. We support a national and international community of more than 2000 scientists in the fields of physics, chemistry, materials science, geology, engineering and biology. Operating a 24/7 regime we currently schedule 5 cycles of approximately 30 days each and routinely accelerate beam to two targets simultaneously by way of time slotting. An overview of ISIS operations will be presented. |
Abstract Title: Recovery of the Fire Accident at PEFP Speaker Name: Bum-Sik Park Email: bspark@kaeri.re.kr Session: Recommissioning or Decommissioning Abstract Type: talk Abstract: The PEFP(Proton Engineering Frontier Project) is developing a 100MeV proton linear accelerator and 10 beamlines. A 20MeV linac was installed, tested and operated in KAERI(Korea Atomic Energy Research Institute) site before the site construction. On the early morning April 9, 2009, a fire accident occurred in the building where the accelerator was operated. The flame did not occur in the linac space. But the damage for equipment was not from the heat but from the adhesive ashes. It took five months to overcome the fire accident. The recovery process will be reported. |
Abstract Title: Commissioning Results and First Operation at ALBA Synchrotron Light Source Speaker Name: Montserrat Pont Email: dperez@cells.es Session: X-Ray FEL Operation Abstract Type: talk Abstract: ALBA is a 3 GeV synchrotron light source, located in Barcelona (Spain) which was commissioned during 2011 and has started users operation in 2012. Up to 3000 h will be devoted to users operation in 2012. This operation is ensured by a crew of operators assisted by the rest of the Accelerator Division. The main results for the commissioning will be presented and also the details on how the operation has been organised will also be given. |
Abstract Title: Training at the Advanced Light Source Speaker Name: Bloemhard Patricius Email: brick@lbl.gov Session: Operator Development Abstract Type: talk Abstract: The ALS is a 1.9 GeV Electron Storage Ring Light Source. With more than 40 beamlines in use for scientific experiments, it is a complex facility with a lot of daily activity. We've recently changed from a three times per day fill \ beam decay mode to an automated continuous beam injection mode. This changed the work and training loads for our operators. They now have a wider a variety of duties that include running the accelerator and administrative control of beamline safety. Teaching new operators all of the background information, the documented procedures we use and providing the hands-on experience required to do these tasks independently used to take about one year. Adding structured methods and a more carefully laid out program not only reduced qualification time to about nine months but also provides a larger skill set. |
Abstract Title: Are you customer focused? – User specified Control System Modifications for the Argonne Tandem LINAC Speaker Name: Maria Power Email: mpower@anl.gov Session: Automation Abstract Type: poster Abstract: Applying customer focused management policies is a key to success in any organization. The primary customer of the control systems group at the ATLAS accelerator is the operations group which provides beam to the experiments. Occasionally, special experiments and beam development projects also have requests and needs that affect the entire control system. The benefits of a customer focus and recent modifications to the ATLAS control system for these groups will be discussed. |
Abstract Title: Reorganizations, Program Changes and Reduced Funding Speaker Name: Daniel Johnson Email: D_Johnson@fnal.gov Session: Adapting to Changes Abstract Type: talk Abstract: Fermilab’s main users were the Fixed Target experiment’s back in the 70’s and early 80’s. The program changed to mixed Collider and Fixed Target operations when the Tevatron came online. Collider physics dominated operations until the Fixed Target experiments returned in the form of test beams and Neutrino experiments. Each of these program changes have been met with reorganization and manpower adjustments. Recent times of reduced funding have added another variable into the mix. I hope to show how some of these adjustments worked out for the better. Reduced funding on the other hand adds a different aspect to machine operations. |
Abstract Title: Optimizing X-ray FEL performance for LCLS at SLAC Speaker Name: Sean Kalsi Email: skalsi@slac.stanford.edu Session: X-Ray FEL Operation Abstract Type: talk Abstract: SLAC National Accelerator Laboratory’s Linac Coherent Light Source (LCLS), provides high intensity, sub-picosecond X-rays over a range of 400eV to 9.6 KeV. The LCLS utilizes part of the SLAC 3-km linear accelerator to produce low emittance electron bunches from 4 to 13.6 GeV. When guided through a series of undulator magnets, the resultant ‘micro-bunched’ electrons produce SASE-generated coherent X-rays of extremely high brightness for use in atomic, molecular, and material science studies. Optimizing the performance of the SASE FEL beam requires a combination of reliable diagnostics, established measurement techniques, feedbacks to maintain key parameters, and within constraints, the freedom to explore the electron beam longitudinal and transverse phase space. Experience from the first 3 years of LCLS operation will be presented. |
Abstract Title: Adapting to Changes at the SLAC National Accelerator Laboratory Speaker Name: Roger Erickson Email: roger@slac.stanford.edu Session: Adapting to Changes Abstract Type: talk Abstract: SLAC was originally built to explore the constituent parts and forces within protons and neutrons. Now, nearly a half century later, SLAC has evolved into a multi-program laboratory in which the accelerators are used primarily to generate beams of synchrotron light and intense x-ray laser pulses. Along the way, the lab has been reorganized to better match the needs of the new science programs. These changes have posed new challenges and new opportunities in Accelerator Operations. |
Abstract Title: Five years of operation at HIT – a review emphasizing reliability issues Speaker Name: Michael Galonska Email: michael.galonska@med.uni-heidelberg.de Session: Reliability and Availability Abstract Type: talk Abstract: The Heidelberg Ion Therapy Facility (HIT) is the first dedicated proton and carbon cancer therapy facility in Europe. It uses the full 3D intensity controlled raster scanning dose delivery method. The ion energy ranges from about 50 up to 430 MeV/u i.e. ion penetration depths of 20 to 300 mm in water. HIT comprises four high energy beam lines: two horizontal patient treatment rooms (both in operation); a horizontal experimental cave for quality assurance, development, and research work in a broad range of disciplines; and the only heavy ion gantry worldwide (carbon ions up to 430 MeV/u, 6.6 Tm). The beam exit is rotatable by 360 degrees and allows for patient treatment from arbitrary directions. Treatment operations at the gantry will start in autumn of this year. Since spring 2007 the HIT Betriebs GmbH (HIT Operations Ltd., subsidiary of the University Hospital Heidelberg) has been solely responsible for the operation of the facility in a 24/7 scheme as well as for most parts of the maintenance. Thus this paper reflects the 5 years of experience at this new facility. This paper outlines some reliability issues at HIT such as the beam stability (stability of beam position/-size, spillshape, radial beam position under the terms of magnetic field control in the synchrotron), some remarks on beam time statistics and the data handling of a huge amount of device process data, i.e. device data for the different settings of energy, beam size, intensity, ion species, and gantry angle which makes up for more than 100,000 possible beam and device settings. |
Abstract Title: Systems Reliability from Design to Implementation to Long Term Service Speaker Name: Violeta Toma Email: violeta@triumf.ca Session: Reliability and Availability Abstract Type: talk Abstract: Based on experience, TRIUMF learned that ease of service is not always the best for reliability. We moved away from quick connects in water lines and high current lines placed in high radiation areas as we found they were the parts which required service most often. Choice of materials and method of installation is looked at to reduce the need for service of various components. Standardizing components and mounting procedures increases the up time as it allows for faster swapping in case of a failure. We plan to expand on this principle in the construction of the e-linac, currently under way. I will also talk about the implication of inadequate monitoring and long term trending in the cooling systems. |
Abstract Title: The Impact of a Large Scale Power Conditioning on Accelerator Operations Speaker Name: Don McGilvery Email: don.mcgilvery@synchrotron.org.au Session: Reliability and Availability Abstract Type: talk Abstract: At the start of 2012 a large scale power conditioning plant was installed at the Australian Synchrotron light source to provide high integrity power to the cooling and storage ring systems. This has lead to a significant rise in beam availability and many other benefits. There are also some downsides. This talk will highlight both the positive and negative impacts on the Operation of the synchrotron light source. |
Abstract Title: Recommissioning the Fermilab Recycler Ring as a Proton storage ring Speaker Name: Martin Murphy Email: mmurphy@fnal.gov Session: Recommissioning or Decommissioning Abstract Type: talk Abstract: The Fermilab Recycler Ring (RR) was designed as a 2.5-mile (4 KM) permanent magnet storage ring for antiprotons. With the end of Fermilab's collider program the Ring is being recommissioned to serve as a short term (0.75-seconds) proton storage ring. The new mode will allow the Main Injector synchrotron double it's beam power to neutrino experiments. Many subsystems are being eliminated, replaced or repurposed. After an extensive beam commissioning process operators will learn to run the accelerator complex in new and exciting ways. There will be new applications, new modes of injection and extraction, new RF, new controls, and new procedures to develop and learn. |

Abstract Title: Paths to an All Digital Control Room Speaker Name: Michael Costanzo Email: mcostanzo@bnl.gov Session: Poster Session Abstract Type: poster Abstract: The new Main Control Room for the Relativistic Heavy Ion Collider (RHIC) was designed to eliminate the physical presence of dedicated hardware such as oscilloscopes, patch cables, and button panels, in favor of large LCD monitors and standard computer terminals. This arrangement has provided increased flexibility within the control room to accommodate operators, physicists, and specialists, and has increased the capacity for remotely-located staff to interact, troubleshoot, and monitor machine operations. One of the challenges associated with the migration to an all-digital control room is the employment of specialized hardware that can be remote controlled and the translation of real front panels into software-based virtual front panels. This presentation illustrates three examples of such a migration. |
