  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.
