| 摘 要： | 电子清刷是微通道板生产流程中常用的除气方法,会引起微通道板其他性能参量的变化.为研究电子清刷对微通道板输出信噪比及增益的影响,根据信噪比及增益的定义讨论了微通道板性能参量的测试方法,研制了微通道板参量测试系统.应用微通道板参量测试系统对微通道板进行了电子清刷处理,测试清刷过程中不同阶段微通道板的信噪比及增益变化.实验表明:微通道板增益随清刷时间增加而降低,同时增益稳定性提高；电子清刷过程中微通道板的输出信号及噪音的变化率与微通道板增益的变化率基本相同,输出信噪比基本不变.增益变化是影响清刷过程中信号及噪音变化的主要因素,并且电子清刷对微通道板输出信噪比影响较小.

| Abstract: | The microchannel plate (MCP) is a core device of the image intensifier for the characteristic of the electron gain. The electron rinse is a common way in the flow of the microchannel plate produce but it also changed the other characteristics of the microchannel plate. To study the effect of the electron rinse on the output signal to noise ratio and the electron gain of the microchannel plate, the method of the output signal to noise ratio test and the electron gain test based on their definition are discussed. The microchannel plate parameters test system is designed and the microchannel plate is rinsed by electron in the microchannel plate parameters test system. The output signal to noise ratio and the electron gain of the microchannel plate are tested in the process of the electron rinse at different stages. The causation of the variation of the output signal to noise ratio and the electron gain is analyzed. |
