Humanity is about to re-land on the lunar surface after 50 years have past since Apollo 11 landed on the lunar surface. Because there are not an atmosphere and a geomagnetic shield around the Moon, energetic charged particles such like H will hit a astronaut directly without losing most of their energies. For dose management, it is required to develop an energy spectrometer to measure charged particles having over several hundreds MeV. In this talk, I am going to present the status of Geant4 simulation studies on imaging cut condition for Ring Imaging Cherenkov Spectrometer (RICheS).
