Temperature dependence of alkali-antimonide photocathodes: Evaluation at cryogenic temperatures
Cs_{x}K_{y}Sb photocathodes were manufactured on a niobium substrate and evaluated over a range of temperatures from 300 to 77 K. Vacuum conditions were identified that minimize surface contamination due to gas adsorption when samples were cooled below room temperature. Measurements of the photocath...
