Abstract :
High current photocathodes operating in vacuum environments as high as 8×E-5 torr are being developed at Los Alamos for use in a new generation of linear induction accelerators. We report quantum efficiencies in wide bandgap semiconductors, pure metals and compound metal surface photocathode materials illuminated by ultraviolet laser radiation
