MCP-PMT mainly consists of a photocathode, a microchannel plate multiplication system and an anode. The multiplication system contains a single or multiple microchannel plates. When the weak light signal passes through the photocathode, it will excite the photoelectrons, which will be transported to MCP for multiplication under the proximity-focus electric field or the electrostatic focusing electric field. Finally, the amplified electronic signal will be received by the anode and output through the signal line, so as to realize the detection of single photon and other weak signals.
