Microchannel plate (MCP) is a photoelectron multiplier as the core component of low-level light (LLL) image intensifier. MCP has two-dimensional space, time, and energy resolution, fast response time, low background noise, wide dynamic range and high gain characteristics, as well as electrons, ions, UV and soft X-ray photon detection capability directly. In recent years, with the publication of foreign advanced technology and Chinese research staff in-depth understanding of MCP’s unique characteristics, the applications of MCP have extended into many new fields accordingly in China. In addition to the image intensifier, the MCP can be used in deep space exploration and scientific experiments, detecting kinds of trace rays and particles, such as pulsars navigation, nuclear simulation diagnostics, UV, EUV, neutron, neutrino detection and imaging. North Night Vision Technology Co. Ltd (NVT) as the only unit possessing MCP production capacity in China is constantly working on improving, innovation and application research on MCP technology. In this paper, based on the researches on MCP in some new fields the NVT Company has undertaken and ongoing, the technological breakthroughs and application research progresses achieved are described.
