Achievement of 200,000 hours of operation at KEK 7-GeV electron 4-GeV positron injector linac Open
KEK electron positron injector LINAC initiated the injection operation into Photon Factory (PF) light source in 1982. Since then for 39 years, it has served for multiple projects, namely, TRISTAN, PF-AR, KEKB, and SuperKEKB. Its total oper…

Commissioning Status and Plan of SuperKEKB Injector Linac Open
Toward SuperKEKB project, the injector linac upgrade is ongoing at KEK in order to deliver the low emittance electron/positron beams with the high intensity and small emittance. In the September of 2013, the injector linac commissioning ha…
