摘要
防离子反馈微通道板过渡载膜的去除对其性能和质量有重要影响。本文分析讨论和实验研究了硝化纤维素膜的去除技术。采用氢气保护热处理和紫外辐照法去除硝化纤维素过渡载膜,使用XPS、体电阻和电流增益测试分析了处理过程中的表面成分和性能变化,讨论了硝化纤维素膜成分去除和微通道板性能保持的问题。认为氢气保护热处理和紫外辐照能有效去除硝化纤维素膜成分。
The removal of a transition film from an ion-proof microchannel plate affects the performance and quality of the latter.In this paper,the removal technology of nitrocellulose transfer membrane is studied theoretically and experimentally.A nitrocellulose transition film was removed by hydrogen reduction heat treatment and ultraviolet irradiation.The surface composition and properties of the nitrocellulose were measured and analyzed by X-ray photoelectron spectroscopy,plate resistance,and current gain test.The removal of nitrocellulose and the performance of the microchannel are discussed.It is discovered that both hydrogen reduction heat treatment and ultraviolet irradiation can effectively remove the nitrocellulose membrane and sustain the stable performance of the microchannel plate.
