3. Observations on Geant4 at ESA: • Extensive use in Space Science (starting from XMM-Newton in 1997; thereafter LISA, INTEGRAL, BepiColombo, GAIA…) • Emerging use in Manned (ISS) and Exploration missions • Certain further developments needed in Geant4 physics and other kernel capabilities for the above; e.g. further low-energy extensions and heavy ion transport capabilities • Earth Observation, Telecommunication, Navigation, and generic platform technologies: Application domains where materials and components engineering issues are prominent, and where often the industry, rather than academia, has the main role in doing radiation analyses. • => Geant4 is, in principle, in good position to further expand to the above domains • => Need for easy-to-use engineering tools, interfaces and applications utilising Geant4 physics and other capabilities allowing rapid radiation analyses (a la MULASSIS, SSAT, GRAS,…), addressing the radiation effects on new technologies.

4. Ongoing developments • Maintenance phase of MULASSIS, SSAT, and RDM ongoing (QinetiQ, BIRA, ESTEC) • Further GRAS developments and applications, e.g. ConeXpress (ESTEC) • DESIRE Project (KTH Stockholm + collaboration) • Geant4-DNA Project (INFN Genova + collaboration) • Predicting Displacement Damage Effects in Electronic Components by Method of Simulation (University of Cologne) • Integrated Radiation Environment, Effects and Component Degradation Simulation Tool ongoing (LIP Lisbon) • Radiation Environment Research from Multiple Monitors ongoing (ONERA, BIRA, UCL, QinetiQ, DMI, Paul Bühler, ESTEC) • Radiation Effects on Advanced Technologies – Models and Software (Part I) started in 2005 (QinetiQ, BIRA, Rhea Systems, University of Bern) [+expert consultancy budget]. Some work on CAD interfaces SPENVIS-GEANT4 Space Users' Workshop

5. Planned developments • Radiation Effects on Advanced Technologies – Models and Software (Part II) planned to start in 2006 in DN with the team above + other proposers for Part I [+expert consultancy budget] • MEO Electron Environment Models development, to be started in 2006 • Martian Radiation Environment Models; AO to be published soon. Extension of the developments presented in this Workshop + Geant4 heavy ion hadronic physics work + “active shield” concept analysis. Focus on ESA ExoMars mission. • Preparatory Study of Investigations into Biological Effects on Radiation (AO open) • Long-term R&D roadmap for the Exploration programme existing • ESA signature on the new Geant4 Collaboration Agreement!
