Description

The characteristics of moderator assembly dimension was investigated for the usage of 7Li(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 9.3 cm. Comparable indexes were found for the Li target in a geometry with the MgF2 moderator and Teflon reflector
