Problems solved by technology

[0005] The technical problem to be solved by the present invention is, according to the index requirements of high-performance MCP, to provide a single glass solid side with an outer diameter less than or equal to 25mm, a chamfer angle of 5°-7°, and an aperture of 6-8 μm. MCP manufacturing method with an opening area ratio of 60% to 70% and a thickness of 0.28 to 0.38 mm. The thermal physical properties of the solid edge material used in this method should match the thermal physical properties of the MCP effective area material. The MCP can finally satisfy the condition of vacuum baking at 500℃~540℃ without deformation

Abstract

This invention discloses a manufacturing method for micro-channel plate with solid edges including; selecting single glass as the material of the solid edge when the skin and core materials of the effective region are determined, drawing hexagon single wires with said selected solid edge material to be arrayed with the hexagon multiple wires of the effective region in lamination and orderly and manufacturing the whole plate of the micro-channel plate with said solid edge material.

Description

technical field [0001] The invention relates to a microchannel plate, in particular to a microchannel plate used in a high-performance micro-light image intensifier. technical background [0002] Microchannel Plate (MCP) is a two-dimensional continuous electron multiplication electric vacuum device, which is composed of many channels with continuous electron multiplication capabilities arranged in a certain geometric pattern. When a certain electric field is applied to its input and output terminals, the extremely weak two-dimensional electronic image can be multiplied or enlarged. Since MCP itself has a certain quantum detection efficiency for most charged particles, some energetic particles and short-wave photons (ultraviolet rays, X-rays, etc.), it can be directly used to detect them. In theory, MCP can effectively detect all particles and electromagnetic radiation. Although MCP has broad application prospects in the fields of scientific instr...
