Abstract

The article presents a method for one-sided etching of channel openings in unetched microchannel plate blanks using dilute hydrofluoric acid. In this work, we used the blanks of MCP 18-10 microchannel plates. The treatment was carried out in 0.2 N hydrofluoric acid solution at room temperature without oscillating or stirring the solution. Following etching, the diameter of channel openings increased by over 10% of the diameter of MCP 18-10 channels, which increased the electron transmission of the device.

在微通道板的通道中形成入口漏斗

文章介绍了一种使用稀氢氟酸对未蚀刻微通道板坯料的通道开口进行单面蚀刻的方法。在这项工作中，我们使用了 MCP 18-10 微通道板的坯料。处理在 0.2 N 氢氟酸溶液中于室温下进行，不对溶液进行振荡或搅拌。蚀刻后，通道开口直径增加了 MCP 18-10 通道直径的 10%以上，从而提高了器件的电子传输率。
