The influence of exposure to air on the quantum efficiency of thin CsI photocathodes
The ageing of a CsI film by exposure to air is discussed.Such exposures may take place during the transfer of a CsIphotocathode from the evaporation vessel to the detector.The current (DC) was measured using a deuterium lamp for UVirradiation.It has been measured as a function of the length of expos...
