Abstract : The hybrid image intensifier can be a viable second source for 'Starlite' scope and 'Crew Served' weapon sights. The report covers a power supply design which enables the hybrid tube to perform when used with a 50 caliber machine gun or the 106 recoilless rifle. In addition to providing proper response, stability and regulation, the design incorporates these special design features. (1) An internal MCP voltage adjustment which allows depot maintenance to increase tube gain with resulting increased field life for the system. (2) Automatic Brightness Control adjustment which accommodates variations in tube screen efficiencies and thereby improves system yield as well as optimizes performance. (3) An external gain control is provided. Items 1 and 2 can be performed without depotting tube and power supply. (Author)
