  1. 9-14 October, 2000 - Annecy 16-20 October, 2000 - Orsay Highlights of It was a busy month for Geant4! 23-26 October, 2000 - Lisbon

  2. Sessions • Jets/Et miss reconstruction • Medical applications • New techniques • Scintillation calorimetry • Simulation • Perspective talks • Bolometry • Cerenkov calorimetry • Crystal calorimetry • Electronics • Ionization calorimetry Tutorials • Physics processes in electromagnetic showers (M. Maire) • Physics processes in hadronic showers (A. Ferrari) • Calorimeter techniques (R. Wigmans) ~150 participants Mostly devoted to hardware

  3. Simulation 1: Modeling Convener: J.-P. Wellisch Geant4 only... No talks on electromagnetic physics! Methodology of Physics Simulation Software J. Apostolakis, S. Giani Object oriented design and implementation of an intra-nuclear transport model L. Bellagamba, A. Brunengo, E. Di Salvo, M.G. Pia Sw engineering OO methodology Transparency of physics Preequilibrium and Equilibrium Decays in Geant4 V. Lara Physics theory and phenomenology Results from validation tests

  4. Simulation 2: Applications Convener: J.-P. Wellisch • Comparison of Testbeam Data of the ATLAS HEC • D. Salihagic • Comparison of GEANT4 simulation of CMS ECAL testbeam experiments • M. Liedl • Geant4 for the ATLAS electromagnetic calorimeter • K. Kordas • Comparison of Experimental Electron Signals with GEANT3 and GEANT4 Simulations for the ATLAS Forward Calorimeter Prototype • R. Mazini • Tuning of Hadron Calorimeter in GEANT4 using testbeam data • S. Banerjee

  5. Medical applications 6 talks: 4 hardware, 2 simulation 5 academic/HEP environment 1 real hospital practice • Effect of voxel size on Monte Carlo dose calculations for typical clinical photons and electron beams • P. Grisel Mora role of rigorous sw engineering in medical applications relevant functionalities new physics results of general interest EGS-based effect of voxel size on CPU empirical tests case-specific results

  6. Software Process Improvement Milestones Comparison Projects Training Kit ~50 participants Kernel Geometry QA Electromagnetic Physics System Testing WG coordinators TSB CB meetings Documentation General Publication • Interactivity • Visualisation • UI/GUI • Analysis Tools • Space Example project • Applications • XMM/Chandra results • TESLA • DNA radiation damage and much more...

  7. Highlights: milestones • Comparison projects • ~same talks as at Calor2000 • ATLAS and BaBar: mostly comparisons between Geant3 and Geant4, first hints of comparisons with data • ALICE: demonstration of usage of parameterised hadronic models • details to be understood (in experimental data, in user code, in Geant4?) • most advanced [unofficial] project is Brachytherapy at IST-Genova • Training Kit • lot of “private” existing material • the workshop Training Project triggered a collaboration-wide effort • Software process improvement • results of the assessment on Design • recommendations for improvement • QA

  8. Highlights: interactivity • Topic of great interest for user communities • Visualisation • UI/GUI • Analysis Tools • Presentations + hands-on activity • “Space Example” Project • equipping a real-life Geant4-based application with advanced visualisation, UI/GUI and analysis facilities • focus for discussions on facilities • playground to identify requirements, test applications etc. • Geant4 + AIDA + Lizard (+JAS, + OpenScientist) • will be released with Geant4 3.0 next month Thanks Andreas!

  9. large non-HEP user community most had never heard of Geant ~300 participants EGS - MCNP dominated HEP was absent • medical • nuclear reactors • radiation protection, shielding Introductory and summary plenary sessions 10 e - g sessions (most crowded, ~ 2/3 conference participants) 8 n - g sessions 7 hadron sessions Poster sessions Tutorials: e - g , n - g and hadron

  10. The zoo NMTC HERMES FLUKA EA-MC DPM SCALE GEM MF3D EGS4, EGS5, EGSnrc MCNP, MCNPX, A3MCNP, MCNP-DSP, MCNP4B Penelope Geant3, Geant4 Tripoli-3, Tripoli-3 A, Tripoli-4 Peregrine MVP, MVP-BURN MARS MCU MORSE TRAX MONK MCBEND VMC++ LAHET RTS&T-2000 ...and I probably forgot some more Many codes not publicly distributed A lot of business around MC

  11. A flavour of the talks • Monte Carlo Simulation of mammography X-ray units: a comparison between different electron extensions of the EGS4 code system • Water cross section sensitivity in the Naiade benchmark using Tripoli-4 • Is the Spencer-Attix cavity equation applicable for solid state detectors irradiated in megavoltage electron beam? • MCNP calculations for the shielding design of a beam tube to be installed at the Portuguese Research reactor • Monte Carlo determination of the radiation field in the thermal column of the Portuguese Research reactor • Monte Carlo modelling of the Belgian materials testing reactor BR2 • KENO3D Visualization Tool for KENO V.a and KENO VI • Energy spectra and dose distributions of a medical linear accelerator simulated with BEAM/EGS4 and MCNP • Coupling MCNP-DSP and LAHET Monte Carlo codes for designing subcriticality monitors for accelerator driven systems

  12. Highlights: e.m. general codes 1 release: Fall 2001 Fortran, C, C++ users won’t need to do any programming from conception through production to publication anybody can run applications without reading a manual EGS5 FLUKA e.m. it stimulated new activity in the field, since for years there have been only ITS and EGS, that were frozen the source will be available in ~1 year thanks to NASA funds

  13. Highlights: e.m. general codes 2 Tripoli4 F77, C, C++ n, e, g validated through comparisons to MCNP and Penelope EGSnrc New EGS4 version e, g Specialised in the low energy domain Penelope MARS Used at Fermilab for accelerator studies

  14. Fast Simulation of X-ray Transition Radiation in the Geant4 Toolkit (V. Grichine) Multiple scattering in Geant4 (P. Arce et al.) On hadronic models in Geant4 (J.-P. Wellisch) + isotope prod. tutorial OO approach to pre-equilibrium and equilibrium decays in Geant4 (V. Lara) Generic design of physics processes in Geant4 (M. Asai) Lot of interest in Geant4!

  15. EG invited talks: • Geant4 15’ • Fluka 15’ • Tripoli 15’ • Penelope 15’ • EGS5 15’ • EGSnrc 15’ Balance Interesting features... Workaholics... Same person • member of the International Advisory Committee • member of the Scientific Program Committee • 1 plenary talk • 3 parallel EG talks • 1 tutorial • chaired 1 EG sessions ...and there were several other similar cases! Fortran, Fortran, Fortran, Fortran, Fortran, Fortran, Fortran, Fortran, Fortran... Lots of comparisons between MC codes (no data...) Epistemology Questions Software engineering: what is? Geant? I’m envious! Memorable quotes 20th century was the century of physics, 21st century is the century of biology! Invited plenary talk What Monte Carlo represents for the USA
