Advances in Vacuum Photon Detectors for High Energy Experiments

摘要

Recent progress on vacuum based photon detectors is reviewed. Even after rapid progress on various solid state detectors, vacuum based photon detectors such as phtomultipliers still play a significant role in many high energy experiments where high speed detection of weak photon signals is critical. The latest development of hybrid devices such as HPD, HAPD, EBCCD and ISPA are reviewed and their advantage over conventional photon detectors is discussed in some detail.
