Problems solved by technology

This form is affected by the physical and chemical properties of the channel substrate glass. After the channel diameter is reduced to a certain extent (below 6um), the solid edge glass 1 will appear in large quantities due to the change of the thermal expansion coefficient of the entire substrate during the MCP production process. The deformation of the microchannel plate affects the quality of the microchannel plate

Abstract

The invention relates to glass for a solid edge of a micro-channel plate. The glass comprises, by weight, 65 to 75 parts of SiO2, 15 to 20 parts of sigma(Na2O+K2O), 8 to13 parts of sigma(CaO+BaO), 0 to 2 parts of Al2O3, 1 part to 5 parts of B2O3 and 0 to 1 part of ZnO. The invention has the advantage that MCP does not deform even when the thermal expansion coefficient of a whole substrate changes in the process of fabrication of MCP.

Description

technical field [0001] The invention relates to a solid edge glass of a microchannel plate. Background technique [0002] Microchannel plate (abbreviated as MCP) is a channel-type electron multiplier device composed of up to millions of regularly arranged fine hollow glass tubes. of. [0003] As the above-mentioned electron multiplier, the MCP detects electrons, ions, X-rays, etc., and has the characteristics of small size and light weight, and has excellent high gain. [0004] Because the shape of MCP is like a thin disc that gathers millions of tiny parallel hollow glass tubes, its mechanical properties are mainly guaranteed by the solid side glass. In recent years, due to the further improvement of the characteristics of MCP such as high resolution and high-speed response, it has been hoped that the channel diameter of MCP will be reduced, the diameter is less than 6um or the channel spacing is shortened, and the thickness of MCP will be correspondingly thinner. Th...
