摘要

According to definition of noise factor of microchannel plate and the test principle, the authors set up a test installation, and measured the numerical values of MCPs which were made of different materials and channel pore including no/with ion barrier film in input of MCP. In order to seek the technical approach to reduce noise factor of MCP at the same time, we tested and analyzed the relation between noise factor and MCP voltage, combined relation between signal-to-noise ratio of GEN. image intensifier and MCP voltage, open out relation between signal-to-noise ratio of GEN. image intensifier and noise factor of MCP with ion barrier film.
