Description
Proton beam irradiation on a cryostat can induce device activation that causes radio protection issues and cryostat transportation delay. The aim of this study, funded by CNES, was to predict the behaviour of a cryostat during and after irradiation using a chain of software tools:
- FASTRAD for cryostat modelling and import to GEANT4,
- GEANT4 for dose and transmitted spectra calculation in different cryostat volumes including DUT, Devices Under Test, located inside the cryostat,
- FISPACT for activation calculation in these volumes based on particle spectra,
- RAYXPERT for radio protection calculation based on these activation data.
Another important point was to assess the TID, Total Ionizing Dose, and TNID, Total Non-Ionizing Dose, deposited on DUT inside the cryostat. The dose results obtained with GEANT4 calculations were compared to real cryostat irradiation measurements performed with an equivalent beam configuration.
