A versatile multiphysics photocathode growth and characterization system is being commissioned by the Applied Cathode Enhancement and Robustness Technology (ACERT) team at LANL. The multiphysics system brings together state-of-the-art surface-science capabilities and leverages unique LANL capabilities to provide an integrated system consisting of (i) bi-alkali antimonide and nitride semiconductor thin-film growth, (ii) advanced surface-science characterization tools, and (iii) incorporation of photocathodes into an operational electron-gun cathode assembly for quantitative beam emittance measurements. Our goal is to provide a modular integrated UHV platform for advancing photocathode performance to the levels needed for the next generation of advanced FELs and accelerators.
