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