Problems solved by technology

[0003] At this stage, the domestic microchannel plate development process is not different from that of 50 years ago.
The high gain and high stability of the glass microchannel plate still exist, but the problems caused by the complicated process are still unsolved, and become increasingly prominent with the improvement of technical requirements
For example, (1) the wire diameter is uneven
In the glass microchannel plate drawing process, the change of the fiber diameter causes the change of the channel diameter, and the consequence is that the imaging image and det

[0038] Another embodiment of the present invention proposes a kind of preparation method of organic material microchannel plate, it comprises:

[0039] Preparation of organic material microchannel plate substrate;

[0040] preparing a conductive layer on the organic material microchannel plate substrate;

[0041] An emission layer is prepared on the conductive layer.

[0042] Preferably, the preparation of the organic material microchannel plate substrate includes: after the organic material film is bombarded by heavy ions, the two sides are respectively irradiated with ultraviolet light for 2 hours to activate the edge of the hole of the organic film, and the side of the irradiated post-irradiation is the end of the macropore, and the symmetrical The electrolytic working cell block made of polytetrafluoroethylene with good performance is cleaned with ultrapure water and then blown dry with nitrogen. Finally, the film was fixed in the module composed of two electrolyzers, an...

Description

technical field [0001] The invention relates to a microchannel plate and a preparation method thereof, in particular to an organic material microchannel plate and a preparation method thereof. Background technique [0002] Microchannel plate (MCP) is the key component of the second, third, and fourth generation image intensifiers and particle detectors currently under development. Its noise is the main noise source of the image intensifier, and the noise of the image intensifier causes the finished product of the image intensifier in my country The low detection rate of the imaging system and the short detection distance of the image tube in the imaging system affect the international competitiveness of my country's micro-channel plate back-end products. , high-resolution microchannel plate has practical guiding significance. Among them, photon scattering and electron scattering are the key factors that cause the background noise of the image tube. Photon scattering is a par...
