Speaker: Petteri Nieminen

  The need to assess the effects of radiation on spacecraft is becoming increasingly important due to the increased sensitivity of microelectronics and sensors and the reduced availability of radiation hard alternatives. Monte Carlo simulation offers the ability to model in detail the physics of space radiation to assess and optimise hardening strategies. Geant4 is a new-generation toolkit for Monte Carlo simulation, intended for a wide range of applications, including space. The current version of this code provides in a single tool comprehensive treatment of the physical processes from PeV energies of hadronic interactions, to <1 keV for electromagnetic interactions and ~eV energies for neutron transport.
  The European Space Agency as part of the Geant4 international collaboration is supporting the development of Geant4 with the objective of making the code the basis of a general space radiation shielding and effects tool (SPARSET). This paper will review the physical processes modelled by Geant4 in the context of the user requirements for space radiation effects analysis. An overview will also be presented of the current and planned developments in Geant4 funded by ESA.
