Abstract :
In the present article, the production process of the photocathodes for the TESLA Test Facility (TTF) at DESY Hamburg and the Photo Injector Test Facility at DESY Zeuthen (PITZ) is reviewed in order to highlight key elements for the final photocathode performances. Since the first photocathode production in 1998, we have continuously collected relevant parameters of the cathode plugs and deposition process. These data are now critically analyzed in view of an optimization of the photocathode performances for the next generation of high brilliance sources.
