Abstract
A general solution to the positive ion feedback problem in Hybrid Photon Detectors (HPD), photomultipliers 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.
