  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.

  In the cERL in­jec­tor cry­omod­ule, elec­tron beams of 10 mA are ac­cel­er­ated from the beam en­ergy of 500 keV to 5 MeV. A three 2-cell cav­ity sys­tem was cho­sen for the cERL in­jec­tor. Each cav­ity is dri­ven by two input cou­plers to re­duce a re­quired RF power han­dling ca­pac­ity and also to com­pen­sate a cou­pler kick. In the cERL in­jec­tor cry­omod­ule, crit­i­cal hard­ware com­po­nents are not su­per­con­duct­ing cav­i­ties but RF input cou­plers op­er­at­ing in CW mode. Six input cou­plers for the in­stal­la­tion in the cry­omod­ule were fab­ri­cated, and three pairs of input cou­plers were care­fully con­di­tioned. Costruc­tion sta­tus, cool-down tests and high power RF test re­sults on in­jec­tor cry­omod­ule for com­pact-ERL at KEK will be dis­cussed in this paper.

  We con­structed a new fa­cil­ity for the fab­ri­ca­tion of su­per­con­duct­ing RF cav­ity at KEK from 2009 to 2011. In the fa­cil­ity, we have in­stalled a deep-draw­ing ma­chine, a half-cell trim­ming ma­chine, an elec­tron-beam weld­ing ma­chine, and a chem­i­cal etch­ing room in one place. We started the study on the fab­ri­ca­tion of 9-cell cav­ity for In­ter­na­tional Lin­ear Col­lier (ILC) from 2009 using this fa­cil­ity. The study is fo­cus­ing on the cost re­duc­tion with keep­ing high per­for­mance of cav­ity, and the goal is the es­tab­lish­ment of mass-pro­duc­tion pro­ce­dure for ILC. This ar­ti­cle re­ports the cur­rent sta­tus of the stud­ies in CFF.
