Abstract
Development of the Interplanetary Radiation Environment Monitor (IREM) to be installed on the Martin Moons eXploration (MMX).
MMX’s flight path is a round trip from Earth to the vicinity of Mars, and its purpose is to measure the radiation environment along this route.

Reasons and benefits of using JAXA Supercomputer System
This is a device that measures the amount of charge generated when radiation (charged particle beam) passes through a silicon detector.By individually measuring the amount of charge of each of the 19 stacked silicon detectors, it is possible to determine the incident energy of radiation.
A huge amount of calculation is required to simulate the entire measurement range using Geant4.
Achievements of the Year
Our goal in 2023 was to try running Geant4, but we were unable to make adjustments to the point where Geant4 would work.
It is planned to continue in the next year as well.
