Microchannel plate photomultiplier tube
Product application: optical analysis instrument, medical instrument, nuclear measuring instrument; high-energy physical detection, cosmic ray detection.
Large-area micro-channel plate photomultiplier tubes are mainly used in neutrino detection experiments, high-energy physical detection fields and single-photon detection fields. Previously, large-area detection type photomultiplier tubes used a metal dynode structure, and a large-area photomultiplier tube with a microchannel plate structure. It is a brand-new product structure with good single photoelectron spectrum peak-to-valley ratio, high quantum efficiency, The advantages of high time resolution are the first in the world.
This product uses Sb-K-Cs cathode as a photoelectric conversion cathode, which has high quantum efficiency for photons in the 400-450nm band; using a microchannel plate as an electron multiplying system, two microchannel plates superimposed can achieve 107 electron gain, microchannel The doubling distance of the board is short, so it has excellent time resolution. Product performance can be customized according to customer needs. At present, the main products are 8-inch and 20-inch microchannel plate photomultiplier tubes.
