Problems solved by technology

However, there is a risk in such a test, that is, once fan-in and fan-out processing is performed on a fast signal of tens of picoseconds (ps), its time information will immediately become very slow, and the fast time characteristic carried by the original signal will be lost, that is, Very fast fan-in and fan-out electronics are difficult to obtain or develop, and the cost is high

Abstract

The invention provides a photoelectric detection anode and a multi-anode photomultiplier, and relates to the technical field of photoelectric detection. The photoelectric detection anode comprises a position detection layer and a time detection layer, the position detection layer comprises a metal plate, the metal plate comprises a plurality of areas, each area is provided with a metal needle, the metal needle of each area is connected with a first signal reading device, and the first signal reading device is connected with a second signal reading device. The position acquisition module is used for acquiring position information by acquiring charge quantity of signals; the time detection layer comprises at least one metal wire, the end part of the at least one metal wire is connected with a second signal reading device, and the second signal reading device is used for acquiring time information by collecting waveform data of the signals. According to the invention, the position information of the photomultiplier position detection layer and the time information of the time detection layer can be read independently at the same time.

Description

technical field [0001] The present disclosure relates to the technical field of photodetection, and in particular, to a photodetection array anode and a multi-anode photomultiplier tube. Background technique [0002] A photomultiplier tube is a vacuum detection device that converts extremely weak optical signals into electrical signals. Micro-Channel Plate Photo-Multiplier Tube (MCP-PMT) refers to a photomultiplier tube with a micro-channel plate as an electron multiplier system, compared with the traditional electrostatic focusing dynode structure photomultiplier tube. , First of all, the moving distance of electrons from the photocathode to the anode is greatly shortened in structure, and the electron multiplication characteristics of the microchannel plate determine that the photomultiplier tube of this structure has many specific properties, especially it can achieve high Accurate location-resolved and time-resolved. [0003] In the related art, the data readout of the...
