| Abstract | The bialkali-antimonide photoemissive material K2CsSb possesses properties that are well suited for photocathodes in accelerator applications. These include high quantum efficiency and low transverse emittance when illuminated by visible light, robustness in terms of sensitivity to water contamination and long lifetimes when operated under UHV conditions. The primary difficulty identified in producing K2CsSb photocathodes is in the minimization of surface roughness, a phenomenon that is believed to lead to increased emittance and therefore decreased performance. |
