We have used the MCNP code to simulate neutron moderation in the IPNS target/moderator assembly. The goal of this study was to investigate the effect of groove configuration on neutron leakage from the C moderator. This moderator supplies low energy neutrons to four low-Q elastic scattering instruments; two reflectometers and two SANS instruments. The current horizontally grooved configuration is not optimized for the two vertical-slit-geometry reflectometers. This study resulted in a more optimized groove configuration.
