An assembly tooling and assembly method for an electron multiplier dynode

Abstract

The invention belongs to the technical field of vacuum electronic devices, and specifically discloses a dynode assembly tool for an electron multiplier, including an adjustment sheet, and a plurality of limiting grooves for installing a dynode assembly are arranged on the surface of the adjustment sheet And the positioning hole for positioning with the lower substrate; the limit groove matches the shape and position of the dynode assembly. It also discloses an assembly method. When installing, align the adjustment piece with the lower substrate and place it, align the dynode assembly with the limit groove and put it in, then the dynode assembly can be inserted into the lower substrate. The invention has a simple structure and can Auxiliary electron multiplier dynode assembly speeds up the assembly speed, improves the alignment accuracy of each component, shortens the exposure time of the secondary electron emission film on the dynode to the atmosphere, and reduces the pollution of the dynode secondary electron emitter during assembly , thereby reducing the influence of the atmospheric environment on the performance of the electron multiplier during the assembly process.

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...
