本文介绍了微通道板离子阻挡膜在成像器件中的作用,测量了带膜微通道板的探测效率。实验发现,带膜微通道板的探测效率不是膜厚的单调函数。最后,从理论上对带膜微通道板的探测效率进行了半定量分析。
This article describes the role of the microchannel plate ion-blocking membrane in imaging devices and the detection efficiency of the microchannel plate with membrane. The experimental results show that the detection efficiency of the membrane-covered microchannel plate is not a monotonic function of the membrane thickness. Finally, the semi-quantitative analysis of the detection efficiency of the membrane-coated microchannel plate is theoretically carried out.
