  1. Special Geant4 session BGM/OMPC 2008/03/18 Nobu Katayama KEK

  2. Why Geant4? • Geant4 is the successor of GEANT3, the world-standard toolkit for HEP detector simulation • it has a large degree of functionality and flexibility • large user base • it is complex and huge • not particularly optimized for our application • Nonetheless we seem to have no other choice • So we started

  3. Why now? • History at Belle • Tajima/Katayama worked on the first implementation of BelleG4 3-4 years ago • We stopped because we needed to (re)write reconstruction software • Kibayashi/Katayama started to work last year • We were determined to get it going this time • You will see what we have now • We hope you will help us get going from now

  4. Why do we need it for Super Belle? • Optimize the design of each sub detector • Optimize the overall design of the detector • Optimize the design of interaction region with the machine people • Understand the effectiveness of new frontend electronics through simulation • Prepare for the reconstruction software for an immediate use upon startup of the machine

  5. Today’s talks • We asked those who have been working on/using g4superb (Geant4 simulation program for super Belle) to give introductory talks on G4 and g4superb and its use • Geometry and Material (+RICH status) • Hits and digitization (+TOP status) • Physics and transport in G4 (+KLM status) • g4superb in basf (+ECL status) • tracking and overall status (March 20th)
