标题： Solution to the ion feedback problem in Hybrid Photon Detectors and Photo Multiplier Tubes

摘要： 解决混合光电倍增管（HPD）、光电倍增管（PM）和其他类似探测器中正离子反馈问题的通用方法是插入一个永久静电势垒，该势垒防止正离子从阳极或第一倍增极向光电阴极漂移。 在本文中，我们介绍了该方法在Intevac HPD中的应用。 显示英文摘要

摘要： A general solution to the positive ion feedback problem in Hybrid Photon Detectors (HPD), photo multipliers (PM) and other similar detectors was found in the insertion of a permanent electrostatic potential barrier which prevents drift of positive ions from the anode, or the first dynode, towards the photocathode. In this paper we present the method as applied to the Intevac HPD.
