A photo-cathode research laboratory has been constructed at SLAC to test and characterize the spare LCLS electron gun. At the heart of the laboratory is a dual-purpose Ti:Sapphire oscillator/regen laser that can deliver either a 2.5ps, 760nm beam to the photocathode gun or a 35fs, 800nm beam to prototype diagnostics for the LCLS. The objective of the photocathode research is to definitively identify ‘recipes’ for high-reliability cathode processing resulting in high quantum efficiency and low beam emittance. The LCLS diagnostics program is presently aimed at developing spectral-encoding systems for shot-by-shot pulse arrival time measurements at the 10fs level. In this paper we review the Ti:Sapphire laser system and report on status of the photocathode and diagnostics programs. | ||
