New solution for the ion feedback problem, ĐĐ applied to the Intevac hybrid photon detector ĐĐ for the MAGIC cosmic gamma ray telescope

A general solution for 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 towards the photocathode. In this paper we present the application of the method to the Intevac HPD.
