Photocathodes play a key role in all photo-injector systems.

Built for LCLS-II HE SRF gun project (2022-2025)

Cathode Transfer System

The photocathode transfer system includes the fixed transfer chamber, load locking units and the movable transport chambers. The fixed transfer chamber with a long micrometer accurate bellow allows us to exchange cathodes quickly without warming up the cavity. The movable transport chambers with all-metal valves transport the photocathode in vacuum between the photocathode preparation laboratory and the SRF gun.
