Abstract
A Prompt Gamma Neutron Activation Analysis (PGNAA) system with a LaBr_3 detector was built at the #1 radial beam port of Xi'an Pulsed Reactor. This system was designed to test the feasibility of the application of LaBr_3 detector in nuclide identification using PGNAA method. The prompt gamma spectrum of a sample irradiated by neutron beams was measured. The results were analyzed by a self-developed program, and the nuclides (^<35>Cl, ^<159>La, ^1H, ^<207>Pb, ^<63>Cu and ^<56>Fe) in the sample were identified. It indicates that the LaBr_3 detector can be expected to do material inspection using PGNAA method in further application.
