Problems solved by technology

[0005] The purpose of the present invention is to provide a large-area microchannel plate-type photomultiplier tube testing device, which solves the problem that the traditional photomultiplier tube testing device cannot test the overall performance of large-scale photomultiplier tubes well, and cannot accurately test large-scale photomultiplier tubes due to the influence of the geomagnetic field. Large-scale photomultiplier tubes, limited test space cannot realize batch testing of large-size photomultiplier tubes

Abstract

The present invention provides a large-area microchannel plate type photomultiplier testing device. The device includes a light source system, an electronic system, a darkroom and a computer; the light source system uniformly transmits light emitted by a light source to a plurality of light source conversion devices through an integrating sphere and a one-to-many optical fiber; the light source conversion devices receive the point light source of the optical fiber and outputs uniform surface light sources; and each surface light source illuminates the total cathode surfaces of one large-size photomultiplier. According to the large-area microchannel plate type photomultiplier tube testing device of the invention, the overall performance of a plurality of large-area photomultipliers can be simultaneously tested on the basis of the electronic system and computer test software. With the large-area microchannel plate type photomultiplier testing device adopted, the batch test work of the overall performance of the large-size photomultipliers can be well completed, the compliance of the test environment and use environment of the large-size photomultipliers can be improved, the batch test efficiency of the large-size photomultipliers can be improved, the limitations of a point light source test system are eliminated, and the problem of low efficiency of a point-source scanning test system can be solved.

Description

technical field [0001] The invention relates to the technical field of photomultiplier tubes, in particular to a large-area microchannel plate type photomultiplier tube testing device. Background technique [0002] A photomultiplier tube is a vacuum device that converts weak optical signals into electrical signals. It is widely used in optical analysis instruments, medical instruments, oil logging, space exploration, high-energy physics, laser applications and other fields. It involves many industries in the national economy, especially the application of important projects such as "Shenzhou Spaceship", "Shenguang III", "Ultraviolet Communication", "Small Warhead", "052 Missile Destroyer", and neutrino detection. [0003] With the increase of neutrino detection experiments, the demand for large-scale photomultiplier tubes is increasing, especially for 20-inch photomultiplier tubes. For the Jiangmen neutrino detection experiment led by the Institute of High Energy Physics, C...
