Abstract

The invention provides a vacuum ultraviolet photomultiplier testing device, which comprises a vacuum system, a testing clamp, a light source system, a data acquisition and control system and a computer system, wherein the vacuum system provides vacuum degree requirements for testing, a vacuum ultraviolet photomultiplier is arranged in the testing clamp and is integrally arranged in a vacuum cavity, the light source system is used for providing a test light source of the vacuum ultraviolet photomultiplier, generating an ultraviolet light source and irradiating the ultraviolet light source to the cathode surface of the ultraviolet photomultiplier positioned in the vacuum cavity, and the data acquisition and control system is used for controlling test parameters and test configuration of thesystem, reading a system test data value, transmitting the system test data value to the computer system and analyzing and processing data. Through relative testing, dark current, cathode radiation sensitivity, quantum efficiency, anode radiation sensitivity and gain parameters of a vacuum ultraviolet photomultiplier are tested, and a performance testing and evaluating system of the vacuum ultraviolet photomultiplier is perfected.

Description

technical field [0001] The invention relates to the technical field of ultraviolet photomultiplier tubes, in particular to a vacuum ultraviolet photomultiplier tube testing device and method. Background technique [0002] Vacuum ultraviolet can only be applied in a vacuum environment because it is absorbed by oxygen molecules. The wavelength range is 50nm-200nm (VUV band). Due to technical difficulties, the research and application of this band have been neglected for a long time. [0003] In recent years, with the development of modern science and technology, people pay more and more attention to the research of vacuum ultraviolet radiation, and it has been widely used in various fields such as space physics, atmospheric physics, plasma physics, solid physics, photochemistry, biology and medicine. For example, several important spectra in the VUV band are closely related to the electron density of the ionosphere and other related parameters. By detecting the intensity distr...
