The characteristics of moderator assembly dimension was investigated for the usage of Li-7(p,n) neutrons by 2.3-2.8 MeV protons and W(p,n) neutrons by 50 MeV protons. The indexes were the treatable protocol depth (TPD) and advantage depth (AD). Consequently, a configuration for W target with the Fe filter, Fluental moderator, Pb reflector showed the TPD of 5.8 cm and AD of 93 cm. Comparable indexes were found for the Li target in a geometry with the MgF2 moderator and Teflon reflector.
