PROGRESS IN CONSTRUCTION OF THE 35-MEV COMPACT ENERGY RECOVERY LINAC AT KEK

The 35-MeV Compact Energy Recovery Linac (cERL) is a superconducting test accelerator for the future 3-GeV ERL project (PEARL) at KEK. During the past year, we have finished key devices such as a 500-kV DC photocathode electron gun and 1.3-GHz superconductingcavity (SCC) cryomodules for both an injector and a main linac. We installed these devices into a shielding room of the cERL, and carried out high-voltage or high-power tests successfully. A 5-MeV injector of the cERL has been completed and commissioned.
