Description
GaAs-based photocathodes are currently the only viable technology for producing a spin-polarized electron beam at a high enough average current required for particle collider based nuclear and high energy physics experiments. In this work we give an overview on research carried out at Cornell University focused on improving the robustness of GaAs based photocathodes, including: the development of alternative Negative Electron Affinity (NEA) activation recipes, alkali-halide treatment of GaAs surface and gun tests at high average current in the High ElectRon Average Current for Lifetime ExperimentS (HERACLES) beamline.
