Description
This presentation offers an overview of the recent activities and developments within the European Space Agency (ESA) pertaining to Geant4-based tools. ESA has adopted the use of these tools to support a diverse range of applications, such as validating instrument and detector responses, characterizing background noise in scientific instruments, optimizing space radiation shielding, investigating component effects and aiding scientific studies on biological effects and astronaut radiation hazards.
The presentation will focus on ESA's ongoing efforts to develop and enhance several Geant4 tools, specifically GRAS (3D radiation analysis), MULASSIS (1D radiation analysis), PLANETOCOSMICS (cosmic ray showers), and GRAPPA – the GRAS Preprocessor for planetary bodies and asteroids. The discussion will highlight new features and capabilities, including:
• G4 Multi-Threading functionality integrated into GRAS, improving performance and enabling faster simulations.
• ICRP 123 module added in GRAS. This new analysis module, based on fluence to dose conversion coefficients, enhances the precision of simulations of biological effects resulting from space radiation exposure.
• The introduction of Layered Geometry models allows for the study of habitats and human phantoms within the context of Mars and Moon missions, providing valuable insights into radiation protection strategies.
Real applications of these tools will be presented during the session, demonstrating the practical utility of these advancements. ESA's commitment to enhancing Geant4-based tools underlines its pivotal role in advancing space and planetary exploration and in addressing the challenges posed by radiation in these environments. This presentation aims to foster knowledge sharing, inspire further developments, and encourage collaboration within the Geant4 Space Users community.
