This article describes the main components of the glimmer photon counter tube and its difference from the conventional second generation glitch enhancer. Based on the principle of single-channel photon counting technology, the principle and method of photon gain testing, the main parameter of photon counting tube, is proposed. The testing system is established. The photon gain of the photomultiplier tube is measured, and the test results are compared with that of the conventional second-generation micro-image intensifier. The photon gain estimation formula is given.
