For the Lunar-RICheS high-energy section, which is being developed for radiation-environment assessment around the Moon, detector responses were evaluated using Geant4/ComptonSoft-based Monte Carlo simulations. Using the obtained simulation data, a DSSD alignment method for estimating relative position and orientation misalignments between detector planes was investigated. The residual misalignment after correction and the track-reconstruction accuracy were also evaluated.
