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 ...

Introduction: In radiation therapy with high-energy photon beams (E > 7 MeV) neutrons are generated mainly in LINACs head thorough (γ, n) interactions. These neutrons affect the shielding requirements in radiation therapy rooms. According to the protocol TG-34, photon absorbed dose of 10Gy can cause permanent damage to the pacemaker and the dose of 2Gy can make minor changes in...
