Description
Photocathodes based on the III-V seminconductor GaAs are used as photo-electron sources to supply spin-polarized electron beams for accelerator applications. In order to achieve a sufficient electron yield, a thin surface layer of cesium combined with an oxidant is applied onto the cathode surface. This process is called the cathode activation and is typically done manually by an experienced operator. This contribution presents the ongoing development and testing of an adaptive algorithm and interface for automated activation at the Photo-CATCH test stand.
