  1. Outlook: 2010 & beyond John Apostolakis

  2. Overview • Application areas • HEP, Nuclear, Rare Event • Medical physics • Space applications • Challenges of success • Effort for maintenance • Some trends • Tools / applications based on Geant4 • Future platforms • Note: this is a personal perspective

  3. HEP • First LHC data and comparisons are upcoming • Geant4 is being used for two hadronic calibration schemes by ATLAS • First focus on understanding detectors • Lots of data will be compared with Geant4 predictions (against G4 9.2 patch1 or 2 – at least initially ) • Challenge of lots of feedback • Potential need to use alternative physics models, if differences are found • Some experiments may consider using the improved modeling available in G4 9.3 • Reduced effort on the comparisons with important test beams • Risk to lose these yardsticks – which are cleaner & easier to understand

  4. Medical Physics • Established uses in • Imaging • Proton Therapy • Emerging use in the hot/challenging area • Ion Therapy • Competition is stiff • Geant4 has improved and is very competitive • Many uses in Research are well established • Increasing use in checking treatment planning for protons • Hot area, with many developments ongoing

  5. Applications built on Geant4 • Growing trend • We have seen new ones at this meeting • Partial list • GATE, ptsSim, Gamos • G4BeamLine, BDSsim, .. • Slic (new) • Offer starting point that speaks the language of the domain • Allows people familiar with the domain to start ‘fast’ • Tool to get answers for a defined set of problems • Some users migrate to use Geant4 directly

  6. Some considerations Strengths Challenges Openness Flexibility Physics Functionality Configurability Tools Steep learning curve Guidance needed Challenge to Document

  7. The future platforms • Today 8 core CPUs • Next year 16 cores • In a few years • 100 cores or threads on a chip • 1000 pipelines processing units ( GPUs + CPUs )
