Photocathode development and spectral response measurements at HZB — •Martin A. H. Schmeißer, Julius Kühn, Thorsten Kamps, and Andreas Jankowiak — Helmholtz-Zentrum Berlin

Photocathodes of the Alkali Antimonide group are promising candidates for the generation of electron beams with high brightness and high average current in photoinjectors. A preparation and analysis system for these cathodes was commissioned at HZB and first results are presented. The system supports the in-situ characterization of cathodes regarding their spectral response, and depth-profiled chemical composition using XPS and LEIS.
