Abstract

This paper presents invesigation findings of electron-beam influence on parameters and characteristics of trialcali and bialkali photocathocles of vacuum photoelectric devices and electron-beam amplification channels modification of microchannel plate image intensifier (MCP) of the electrooptical transducer. The electron-beam processing (EBP) increases total sensitivity by 10 - 12% and reduces spoilage in photocathode production to a fourth. The noise factor of MCP subjected EBP before recovery procedure MCP, reduces in 1.5 - 2.0 times, the sensibility of electrooptical transducer increases.
