Welcome to KEK e+/e- Linac

KEK e+/e- Linac injects 8GeV electrons and 3.5 GeV positrons to the KEKB (B-Factory) ring. It also provides 2.5 GeV positrons / electrons to PF (Photon Factory) and PF-AR. The slow positron facility in Linac is being upgraded. The picture on the right shows the beam switch yard at the end of 600m-long Linac.
