Reasons and benefits of using JAXA Supercomputer System
JAXA super computer system was used for the fast simulation calculations using Particle and Heavy Ion Transport code System (PHITS).
Achievements of the Year
To evaluate doses on the D-Space dosimeter installed on the OMOTENASHI, the geometries were prepared for both OMOTENASHI and D-Space, and the doses at the Si sensors placing inside the dosimeter were calculated under the isotropic irradiation of galactic cosmic rays (GCRs). For OMOTENASHI, four geometries with different accuracy levels were prepared and used. As a result, the doses at the Si sensors depended on the accuracy levels of the geometries. It seems to be important to better reproduce the shilding environments surrouding the Si sensors for more accurate simulations.
