Electron multiplier dynode assembling tool and method

Abstract

The invention belongs to the technical field of vacuum electronic devices, and particularly discloses an electron multiplier dynode assembling tool which comprises an adjusting piece, and a pluralityof limiting grooves used for installing dynode assemblies and positioning holes used for being positioned with a lower base plate are distributed in the surface of the adjusting piece, and the limiting grooves are matched with the dynode assemblies in shape and position. The invention further discloses an assembling method, during installation, the adjusting piece is aligned with the lower substrate, the dynode assemblies are aligned with the limiting grooves to be placed in, then the dynode assemblies can be inserted into the lower substrate, the structure is simple, dynode assembling of an electron multiplier can be assisted, the assembling speed is increased, the alignment precision of all the assemblies is improved, the time for exposing a secondary electron emission film on the dynodeto the atmosphere is shortened, and the pollution to a dynode secondary electron emitter during assembly is reduced, so that the influence of the atmospheric environment on the performance of the electron multiplier in the assembly process is reduced.

Description

technical field [0001] The invention belongs to the technical field of vacuum electronic devices, and in particular relates to an assembly tool and an assembly method of an electron multiplier dynode. Background technique [0002] Atomic clocks are the core equipment for timekeeping and time service in various countries. They are widely used in military navigation and positioning systems, time-frequency measurement stations and time-frequency websites, and satellite civil navigation. They are one of the core loads of satellite navigation global positioning systems. Atomic clocks mainly include rubidium clocks, hydrogen clocks and cesium clocks. Among them, the cesium clock has high precision, the best long-term stability, and high reliability. It is used in navigation and deep space exploration, etc. At the same time, the ground station of the navigation system also uses a large number of small cesium clocks. [0003] As the core component of the cesium atomic clock, the el...
