Problems solved by technology

[0003] For the installation process before the superposition test of the double-chip micro-channel board, especially when the two micro-channel boards need to be separately applied voltage, more electrodes and insulating rings need to be installed, and the two micro-channel boards need to be changed during the test. When the mutual position of the channel plate, all the electrodes and the micro-channel plate need to be dismantled and reinstalled, the testing and installation process is complicated
In view of the scratches and discharges that are unavoidable during the installation and testing process of double-chip micro-channel plates, it is impossible to achieve non-destructive installation
In the process of double-chip micro-channel plate stacking test, the control of parameters such as the distance between two micro-channels is inaccurate and prone to errors, resulting in inaccurate results

Abstract

The invention discloses a device and a method for double-piece micro-channel plate superposition testing. The testing device comprises a vacuum pump group, an electronic/ion source, and a tube shell and signal detection system for double-piece superposition micro-channel plate test. According to the device, the micro-channel plates of the double-piece superposition structure can be tested, the distance between the two micro-channel plates is controlled, voltage regulation and control are conducted on the two micro-channel plates respectively, the micro-channel plates are convenient to installand take out, damage to the micro-channel plates in the test process can be reduced, the relative positions of the two micro-channel plates can be conveniently converted, and the micro-channel platesdo not need to be reinstalled.

Description

technical field [0001] The invention relates to the technical field of micro-channel plates, in particular to a device and method for superposition testing of two micro-channel plates. Background technique [0002] The micro-channel plate is a key component to realize low-light night vision technology. It is a compact two-dimensional array composed of many channel electron multipliers. It has a thin-sheet honeycomb structure. The inner surface of the hollow glass fiber has a resistive two- The sub-electron emission layer can multiply electrons tens of thousands of times. This layer is connected to the input and output electrodes of the micro-channel plate. This kind of hollow glass is called a micro-channel, and its channel diameter is generally 5 μm to 12 μm. The gain of the micro-channel plate refers to the ratio of the output current to the input current of the micro-channel plate. Different application scenarios have different requirements for the gain of the micro-chann...
