Gated micro-channel plate photomultiplier tube is a kind of photomultiplier tube with gated function. The detector module using this device can select the desired signal from the strong background light, and can also eliminate possible damage to itsself by strong laser. This detector can be widely used in nuclear physics detection, satellite laser ranging, time-dependent fluorescence afterglow measurement and other fields. External gated micro-channel plate photomultiplier tube modules were successively developed, and the key technical issues such as the lifting of pulsed peak current, the optimization of noise induced by gate pulse and the realization of high electron gain were also solved. The detector module is preliminarily applied to the measurement of CSNS counter-angle white light neutron source, and its gating test function is realized.
