  In KEK, two syn­chro­tron light sources have been op­er­ated. One is the 2.5 GeV Pho­ton Fac­tory stor­age ring (PF-ring) and the other is the 6.5 GeV Pho­ton Fac­tory ad­vanced ring (PF-AR). In this paper, pre­sent op­er­a­tional sta­tus and re­cent R&D ac­tiv­i­ties such as fast local bump sys­tem for he­lic­ity switch­ing un­du­la­tor, hy­brid in­jec­tion sys­tem, pulsed-sex­tu­pole in­jec­tion, etc. Futher­more, up­grade plan to­wards the top-up in­jec­tion of 6.5 GeV PF-AR ring is un­der­way. Con­struc­tion of the straight in­jec­tion tun­nel from linac to PF-AR will be started next fis­cal year. De­sign de­tail and strat­egy for the in­jec­tion scheme will be re­ported.

  The 35-MeV Com­pact En­ergy Re­cov­ery Linac (the Com­pact ERL or cERL) is under con­struc­tion at the High En­ergy Ac­cel­er­a­tor Re­search Or­ga­ni­za­tion (KEK) in Japan. With the Com­pact ERL, we aim at es­tab­lish­ing cut­ting-edge tech­nolo­gies for the GeV-class ERL-based syn­chro­tron light source. To in­stall the ac­cel­er­a­tor com­po­nents of the cERL, we have con­structed a shield­ing room hav­ing an area of about 60 m x 20 m. We have then in­stalled a 500-kV DC pho­to­cath­ode gun, a 5-MV su­per­con­duct­ing (SC) cry­omod­ule for the in­jec­tor, a 30-MV SC cry­omod­ule for the main linac, and some of the other com­po­nents. High-power test on the main SC cry­omod­ule is un­der­way in De­cem­ber, 2012. High-power or high-volt­age tests on the in­jec­tor cry­omod­ule and on the DC gun are planned dur­ing Jan­u­ary to March, 2013. An in­jec­tor of the Com­pact ERL will be com­mis­sioned in April, 2013. We re­port the newest sta­tus of its con­struc­tion.
