Approaches are adopted for obtaining accurate neutron beam parameter and saving the computing time. For the radiation shielding design, the optimizing factors include the cost, weight, volume, machining convenience and background radiation at the detector position. Low background spectrum and high sensitivity are expected. The simulation results, and experiences from international PGNAA community, were used in the design of the CARR PGNAA system.
