Abstract

The invention provides a method and device for hydrogen reduction of a microchannel plate, comprising: a cylindrical quartz reaction chamber; a first electrode and a second electrode arranged at both ends inside the reaction chamber; a hydrogen supply device; a nitrogen supply device ; The DC power supply and the plasma pulse generator supply power to the first electrode and the second electrode through the wires respectively, and form a DC electric field to act on the hydrogen to generate plasma hydrogen, so that the plasma hydrogen can reduce the PbO in the microchannel plate Reaction: a heating device is located outside the cylindrical quartz reaction chamber, the heating device is connected to a controller, and the controller is used to control the heating of the heating device to raise the temperature of the reaction chamber to a set temperature. The invention makes full use of the activity of plasma hydrogen in a vacuum environment, strengthens the reduction reaction of the metal oxide PbO in the microchannel plate, can realize effective reduction at a lower temperature, reduces process time, and accelerates product turnover in actual production .

Description

technical field [0001] The invention relates to the technical field of microchannel plates, in particular to a method and system for hydrogen reduction of microchannel plates by plasma treatment. Background technique [0002] Micro Channel Plate (MCP) is a component that multiplies the electron flow distributed in two-dimensional space. From the structural point of view, it is a porous two-dimensional fiber array composed of millions of hollow fiber tubes arranged in parallel. . Its appearance is generally a circular sheet with a diameter of 20-100mm and a thickness of 0.2-0.5mm. The inner wall surface of each hollow tube channel in the middle working area of ​​the MCP has secondary electron emission performance, realizing continuous electron multiplication function. In particular, the two ends of the MCP are plated with a nickel-chromium metal film to act as electrodes, and the outer ring of the MCP is a solid edge without a channel, which can provide good end-face contac...
