The large-area MCP-PMT is a vacuum electronic device that converts extremely weak light signals into electrical signals. It is a large-area, high-detection efficiency electrostatic focusing pho - tomultiplier tube with independent intellectual property rights. This product uses Sb-K-Cs cathode as a photoelectric conversion cathode, which has high quantum efficiency for photons in the 350-450nm wavelength, using a microchannel plate as an electron multiplier tube system, the superposition of two microchannel plates can achieve an electron gain of more than 107 , The multiplication distance of the microchannel plate is short, so it has superior time resolution. Product performance can be customized according to customer needs. At present, the main products are 8-inch and 20-inch MCP-PMT.
