Despite the shielding of the spacecraft payloads, the internal charging events are resulting from the high energy electrons accumulation inside thick dielectrics. On long time scales, this can create IESD (internal electrostatic discharges). This internal charging phenomenon, potentially leading to part or system failure, is well known to spacecraft designers and requires efficient shielding...

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...

Geant4 is a vital tool for understanding and calibrating the response of space-borne radiation sensors at The Aerospace Corporation, and for understanding the space radiation environment that they measure. In the year and a half since the last Geant4 Space Users’ Workshop, we have used the code to continue to refine our understanding of the response, both foreground and background, of sensors...
