The aim of this work is to help inform the decision for choosing a convenient material for the PGAA(Prompt Gamma Activation Analysis) collimator plug to be installed at the tangential channel of theMoroccan Triga Mark II Research Reactor. Two families of materials are usually used for collimatorconstruction: a mixture of high-density polyethylene (HDPE) with boron, which is commonly used tomoderate and absorb neutrons, and heavy materials, either for gamma absorption or for fast neutronabsorption. An investigation of two different collimator designs was performed using N-Particle MonteCarlo MCNP6.2 code with the ENDF/B-VII.1 and MCLIP84 libraries. For each design, carbon steel and leadmaterials were used separately as collimator heavy materials. The performed study focused on both theimpact on neutron beam quality and the neutronegamma background at the exit of the collimator beamtube. An analysis and assessment of the principal findings is presented in this paper, as well asrecommendation
