Fast FPGA algorithm for neutron–gamma discrimination

Various pulse shape discrimination methods have been used to solve the neutron-gamma problem. But most of them are limited off-line calculation due computation amount and FPGA performance. In order realize real time discriminating neutron gamma, a new algorithm based on traditional was proposed in this paper. The takes into account physical properties signal, which greatly reduces dead without losing precision, can work directly. It has good performance actual experiment CLLB scintillation detector.
