摘要:

NaI and CsI protective coatings on visible cesium‐antimony photocathodes have been studied. With NaI protective films the photocathodes are shown to withstand exposure to considerable doses of oxygen and dry air. This opens the way to their handling and operation in gas media. ©1996 American Institute of Physics.
