Description
In this manuscript, we investigated the possibility of cerium-doped galuminum gallium garnet (GAGG: Ce) coupled to an ultrafast photomultiplier tube (FPMT) to achieve neutron gamma discrimination. The rise time of the FPMT used in this manuscript is 100ps, and the Transit Time Spread (TTS) in single-photon mode can reach 46ps, which can distinguish neutron signals from gamma signals. Using a high-sampling oscilloscope to sample the FPMT waveform, it was found that the waveform with a longer decay time was split into a single-photon waveform. And through the rise time, fall time, amplitude, pulse width and other information to select the waveform combined with pulse shape discrimination method to achieve neutron gamma identification based on GAGG crystal.
