Embodiment 2

[0094] Embodiment 2: the corrosion process of BJ type microchannel plate

[0095] Fill the corrosion tank with a nitric acid solution with a concentration of 1 equivalent, place the microchannel plate to be corroded in a rotary corrosion device, immerse it under the liquid surface, and start the rotary corrosion at a speed of 60 minutes / r for 30 minutes. minute.

[0096] After 30 minutes, the rotating device was stopped, and the liquid level in the corrosion tank was discharged to just submerge the microchannel plate, and then filled with 1 equivalent of nitric acid, and the next rotation corrosion was started after repeated twice, and the time was 30 minutes.

[0097] After 30 minutes, the rotating device was stopped, and the liquid level in the corrosion tank was discharged to just submerge the microchannel plate, and then filled with 1 equivalent of nitric acid, and the next rotation corrosion was started after repeated twice, and the time was 30 minutes.

Abstract

The invention provides a rotary micro-channel plate etching device and an etching method. The rotary micro-channel plate etching device comprises a motor, a hydraulic transmission assembly, a tray, aquartz etching clamp, a liquid supply and discharge system and an ultrasonic device, wherein the hydraulic transmission assembly is provided with a hydraulic transmission shaft; the tray is used for placing an etching clamp and is connected with the hydraulic transmission assembly; the quartz etching clamp is arranged in an etching tank on the tray; the ultrasonic device is used for cleaning the micro-channel plate; the torsion output by the motor is applied to the tray through the hydraulic transmission assembly, the tray is driven to rotate in the circumferential direction, the hydraulic transmission assembly is a liftable hydraulic transmission assembly, and the tray is driven by the hydraulic transmission assembly to ascend and descend to enter and disengage from the etching tank; theetching tray and the motor are arranged on the upper side and the lower side of the etching liquid level through a hydraulic connecting rod assembly, the liquid in the etching tank completely submerges the quartz etching clamp in the etching process, and rapid etching of the micro-channel plate is achieved through rotation of the tray.

Description

technical field [0001] The invention relates to the technical field of preparation of micro-channel plates, in particular to a rotary micro-channel plate etching device and an etching method. Background technique [0002] Microchannel plate is a special optical fiber device, which is an advanced electron multiplier with the function of transmitting and enhancing electronic images. It has the advantages of small size, light weight, good resolution, high gain, low noise, and low operating voltage. , it uses its secondary electron emission characteristics to multiply the electrons colliding with the inner wall (channel) at high speed, so that it can increase the electron flow by more than 10,000 times. Taking advantage of this characteristic, microchannel plates are widely used in photomultiplier tubes, image intensifiers, low-light TVs, X-ray image intensifiers, high-speed oscilloscopes, and photon counting, X-rays, ultraviolet photons, electrons, ions, charged Particles, sub...
