ABSTRACT
Photoelectron transport in (Cs)Na2KSb real space is investigated using the Monte Carlo simulation technique for various photon energies. The quantum yield and modulation transfer function (MTF) of the (Cs)Na2KSb photocathodes, and the energy distribution and transit time spread (TTS) of the emitted electrons have been obtained. In particular, the quantum yield of the photocathode has a good agreement with the measured results. Computed results indicate that the energy distribution spread and TTS of the emitted electrons from a typical (Cs)Na2KSb photocathode are 0.3–0.6 eV and 300–180 fsec, respectively.
