Abstract: Glass composition of microchannel plate (MCP) is optimized to reduce the ion feedback noise of MCP and to improve the image quality and lifetime of image intensifier. The MCPs with optimized glass composition were fabricated by introducing different types and amounts of alkaline-metal oxide as well as adopting high-temperature hydrogen reduction technique. The transfer temperature for the glass is increased; it could be baked at the temperature of over 500℃ and remains stable in electrical performance. The result shows that the internal surface structure of the channel is improved, MCP′s resistance to electron scrub is enhanced, and the gas absorbing is decreased. At last, the further research is proposed.
