The Compact Energy Recovery Linac (cERL) is under construction at KEK for the future 3-GeV ERL project. During the past year, we have finished key devices, such as a 500-kV DC photocathode electron gun and superconducting (SC) cryomodules for the injector and for the main linac. We installed these devices into a shielding room of the cERL, and carried out high-voltage or high-power tests successfully. In the April of 2013, the 5-MeV injector of the cERL was completed. During April to June in 2013, we commissioned the cERL-injector successfully, and carried out beam tuning and studies. We will present the construction and commissioning of the cERL injector, together with the construction status of a return loop.

The 2nd 500 kV DC photocathode electron gun for a ERL injector was constructed at KEK. The gun has new functions such as employ new material for ceramic insulator, insulated anode electrode for dark current monitor, repeller electrode for elimination backward ions, extreme high vacuum pumps and so on. A high voltage conditioning is just begun from this summer. In addition, a new cathode preparation system has been developed. It can prepare three cathodes simultaneously and storage many cathodes in a good vacuum condition. The detail design was finished and the construction of all in-vacuum components is progressing.
