  1. Concluding remarks Makoto Asai On behalf of the SLAC Geant4 team

  2. Contents • Highlights of Geant4 version 9.3 • Following up • SLAC Geant4 team

  3. Highlights of Geant4 version 9.3--- released on December 18th, 2009

  4. ICRU-73 • Implemented migration of ICRU-73 stopping power classes for materials to the G4VIonDEDXTable interface • Access methods of physics vectors have changed (vectors can also be identified via atomic number of material if material is pure) • Classes now deliver mass stopping powers instead of stopping powers per unit length • Removed dependency on ICRU-73 material densities • New utility class G4ExtDEDXTable to handle external electronic stopping power tables for ions

  5. EM physics • Standard EM models • New Goudsmit-Saunderson multiple scattering model for electrons & positrons (e-/e+) • Gamma conversion with LPM effect • Addition of muon multiple-scattering model in Physics Lists • Physics lists with combinations of standard and low-energy models • Introduction of cut in range for recoil • Optical processes • Inclusion of Mie scattering as a new optical photon physics  process • Extension to the unified surface model to have both specular and diffuse components for the transmitted photons • New extended/optical example to exhibit transmission properties of optical fibers with circular and elliptical cross section • Low-energy EM • Complete migration to ‘standard-EM’ design: added Bremsstrahlung physics according to Penelope and Livermore models; added G4LivermoreIonisationModel, first implementation of low-energy ionisation (G4LowEnergyIonisation) in the common design • New DNA processes migrated to the new design; new G4EMLOW-6.5 data set; made obsolete old cross-sections and final-state classes

  6. Hadronics • Models • Developments in CHIPS model to extend its applicability to all energies, particles and targets • Model precise sampling and ‘on-the-fly’ table preparation for coherent_elastic module • Complete improvements to pre-compound model • Allow carbon-ion projectiles in INCL model • Physics lists • New development physics-lists • QGSC_CHIPS (QGS model with ‘EnergyFlow’ interface to CHIPS at all energies) • Interim QGSC_QGSC (QGS model with interface to CHIPS at all energies, still using LHEP for neutrons) • QGSP_FTFP_BERT ( replaces LEP with FTFP for nucleon & pion projectiles) • CHIPS physics list ( completely replaces LEP, also for hyperons) • New physics-lists with special EM options (EMV, EMX, EMY) • Complete and validate INCL/ABLA physics list

  7. gMocren • Great tool available for volume visualization • From JST/CREST project (Japan) to improve Geant4 for medical physics • Able to visualize: • Volume data(including overlay of more than one set) • Trajectories • Geometry • Runs on: • Windows and Linux • Mac will likely happen soon • Based on a commercial package butoffered freely to all Geant4 users • http://geant4.kek.jp/gMocren • Installation is straightforward, follow the Download link on the above page • First run gMocren’s one-click installer • Then, inside C:\Program Files\gMocren\gtk, you will find the one-click installer for gtk

  8. gMocren : A Visualization Tool http://geant4.kek.jp/gMocren/ gMocren and utility software are freely available. 3D (ray casting) 2D (MPR) Opacity curve and color map editor Supported system : - Windows 2k/XP or PC Linux OS - Pentium 4 or faster - more than 1 GB (recommend) free hand or templates with WW&WL editing Particle trajectories Calculated dose distribution Opacity curve and color map editor Functionality Requirements : color mapping • To visualize • - the modality image used by the simulation, • - the calculated dose distribution and • - the particle trajectories • - in an agreeable speed • Transfer function editor • Multi-platform Trajectory information in the simulation is available. contour plot

  9. Platforms supported for 9.3 • Linux SL(C)5, gcc-4.1.2, gcc-4.3.X, 32/64 bits • Linux SL(C)4, gcc-3.4.6, 32/64 bits • MacOSX 10.5/10.6, gcc-4.0.1/gcc-4.2.1 • Windows/XP and CygWin Tools • Compiler Visual C++ 9.0 (Visual Studio 2008) • Also tested: gcc-4.4.X, icc-11.X

  10. Following up

  11. Following up - 1 • Please keep maintaining your Geant4 installation updated. • Irregular patch releases may be more important than regular releases. • Check our web page regularly to find release news, or register to Geant4 announcement mailing list

  12. Following up - 2 • If you have a question • Look for our documents. • Users guides, Twiki pages, tips pages, examples and their READMEs • Post your question on Geant4 HyperNews http://hypernews.slac.stanford.edu/HyperNews/geant4/cindex • Please make sure to do a bit of survey that no one has already asked the same question before. • As the final method, write us a mail. • Avoid anonymous mail account such as hotmail, gmail, etc., if possible. • Mention you attended SLAC Geant4 tutorial 2009. • Or, catch us at meetings/conferences. • Apologies if we cannot recognize you…

  13. Following up - 3 • Near-future events • For space users • Geant4 space users workshop • Aug. 18-20, 2010 @ Seattle • For medical users • G4NAMU annual meeting • @AAPM meeting, Jul. 18-22, 2010 @ Philadelphia • For general users • MC2010 Conference • Oct. 2010 @ Tokyo • IEEE/NSS Conference • Oct. 2010 @ Knoxville, TN

  14. The SLAC Geant4 team • Covers most of the Geant4 categories • Is happy to organize Geant4 tutorial • At SLAC or preferably at your place • Is happy to collaborate with you !!

  15. Thank you for your participation!!
