气体雪崩探测器结合了固体光电阴极和快速电子倍增器，为在非常大的灵敏区域和高光通量下的光子定位提供了一种有吸引力的解决方案。它们提供了单光子灵敏度，并有可能在非常强的磁场下工作。我们讨论了影响气体雪崩光电倍增管工作的主要因素。本文综述了可在气体倍增下工作的碱卤化物和CVD-金刚石紫外光阴极以及新型薄膜保护性碱-锑光电阴极的最新进展，首次为气体光电倍增管在可见光范围内工作提供了可能。提出了适合于这些光子探测器的电子倍增器，并简要讨论了它的一些应用。
Gas avalanche detectors, combining solid photocathodes with fast electron multipliers, provide an attractive solution for photon localization over very large sensitive areas and under high illumination flux. They offer single-photon sensitivity and the possibility of operation under very intense magnetic fields. We discuss the principal factors governing the operation of gas avalanche photomultipliers. We summarize the recent progress made in alkali-halide and CVD-diamond UV-photocathodes, capable of operation under gas multiplication, and novel thin-film protected alkali-antimonide photocathodes, providing, for the first time, the possibility of operating gas photomultipliers in the visible range. Electron multipliers, adequate for these photon detectors, are proposed and some applications are briefly discussed.
