【Abstract】 Microchannel plate(MCP)is a sophisticated electronic optical device.It has advantages of high gain, small size,and low using voltage as a detector.The electronic transmission film on the MCP input plane could effectively avoid the positive ion feedback,and protect the photocathode,eliminate flicker noise,and prolong the lifespan of the device.In conclusion,the different films of the input plane can affect the performance of the MCE Therefore,there is practical value to study surface coating composition of MCP for understanding the relationship between composition and performance and developing high-powered MCP.In the experiment,TOF-SIMS is used to study the surface coating composition of MCP.The results show that there are some main metal elements such as Si,K,Cr,Ni,Rb,Cs,and Pb in the surface of the MCP.更多还原
