9. Internal charging simulation at a Galileo like orbit – effect of the anisotropic shielding and of the environment definition

Mr Pierre Sarrailh (ONERA - The French Aerospace Lab)

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...

15. TRAD’s GEANT4 Activity: Cryostat Study

Mr Pierre Pourrouquet (TRAD)

12/04/2017, 11:30

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...

21. Geant4 Simulations of Space Radiation Sensors and Environment at The Aerospace Corporation

Dr Mark Looper (The Aerospace Corporation)

12/04/2017, 11:55

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...

4. Plans for Using Geant4 in Space Elevator Research

Dr Dennis Wright (SLAC)

12/04/2017, 12:20

The space elevator is a means for moving large amounts of mass into space at relatively low cost. Modern concepts of this structure involve a gravitationally stabilized thin tether made of strong materials such as carbon nanotubes, extending to an altitude of 100,000 km. Along the full length of the tether many hazards, such as space debris, solar storms, radiation damage on tether materials...
