Abstract
A discussion of the possible sources of discrepancies in the measureme nts of the quantum efficiency of CsI photocathodes is presented. We pr opose that the major causes for disagreements in QE are due to the QE dependence on the current density extracted from the photocathode, on the electric field, and on the temperature of the photocathode. Prelim inary results on TMAE enhanced GaAs and Si, plus TMAE protected CsTe a nd SbCs photocathodes, operated in gas, are also presented.
