This article describes a Q crystal fast neutron detector using a pulse shape zero crossing detection technique. The circuit diagram of the zero-crossing discriminator is given in this paper. The characteristics of the work and the problems that should be paid attention to during commissioning are described. The adjustment of the photomultiplier tube is explained. Finally, the performance and index of the detector are given.
