Influence Analysis of Ion Feedback of Microchannel Plate on Image Intensifiers Performance Upgrade and Its Improvement Approach Exploration
摘要
Abstract
The effective quantum availability of image intensifier for several typical image intensifier were evaluated by introducing a conception of noise factor of image intensifier, and the effect of ions feedback of MCP on performance of image intensifier is analyzed. Therefore, the realization of low ion feedback and low noise figure MCP for image intensifier performance to be upgraded to the fourth generation image intensifier merit figure is equally necessary and important for both GaAs photocathode image intensifier and multi-alkali photocathode image intensifier. The remodification of MCP substrate microstructure through the reformulation and devitrification treatment, and restricting ion poisoning resource formation within channel inner surface of MCP substrate, is an effective approach for the realization of low ion feedback and low noise figure MCP.关键词
