Abstract

Abstract: This paper describes the upgraded collimator and shielding design principle for the prompt gamma neutron activation analysis (PGNAA) facility at the Thai Research Reactor. The neutronic calculations with different geometry and material conditions are simulated using the Monte Carlo code. Then, the optimal parameters to maximize the thermal neutrons and minimize background radiations are obtained. The simulation result provides significant contribution in upgrading the PGNAA facility to be available in various applications.
