Test system of biplate cascade microchannel plate photomultiplier static performance

Abstract

The invention discloses a test system of biplate cascade microchannel plate photomultiplier static performance. The system comprises a light source, a constant current source, a combined optical filter box, an integrating sphere, a test camera obscura, a diaphragm, a biplate cascade microchannel plate photomultiplier, a high voltage power supply system, an anode photocurrent tester, a cathode photocurrent tester, an industrial personal computer and a measurement module. By using the system, test work of the static performance of the large area biplate cascade microchannel plate photomultiplier can be well completed, and simultaneously the high voltage power supply system of 11 paths of high voltage output is adopted so as to exert a high voltage on the two groups of biplate cascade microchannel plate photomultipliers, system pertinency is increased and a vacancy of the high voltage system of the two groups of biplate cascade microchannel plate photomultipliers in China is made up.

Description

technical field [0001] The invention belongs to the technical field of neutrino detection, in particular to a test system for static performance of a double-piece cascaded micro-channel plate photomultiplier tube. Background technique [0002] The microchannel plate photomultiplier tube has the characteristics of fast time response, good pulse resolution, excellent anti-magnetic field performance, compact structure, small size, light weight and low energy consumption. It is widely used in counting, plasma diagnosis, time spectrometer and other fields. [0003] At present, double-chip cascaded micro-channel plate photomultiplier tubes are more and more practically used in life and experiments due to their superior performance of high gain and low noise. However, in China, single-chip micro-channel plate photomultiplier tubes are mainly used And the dynode photomultiplier tube test system is mainly used, and there is no system for testing the photomultiplier tube of double-ch...
