1. Maria Grazia Pia, INFN Genova - G4 WG Coord. Meeting, 13/11/2001 ow Energy Electromagnetic Physics ow Energy Electromagnetic Physics New physics features -Model for fluorescence in the continuous part of e/h ionisation -PIXE -Improvements in various physics processes Status: implemented, tested, tagged OOAD: major design iteration -First OO design of data management, cross sections and atomic relaxation -OOD cycle on all e/photon processes Status: implemented, tested, tagged SPI -UR, OOAD, traceability, group process documents etc: all maintained, improved on the basis of feedback from process, in the repository -Reverse engineered event, run, hits+digi, track, processes/management, analysis, particles/management,visualisation (management, model) etc. Status: done Advanced examples -New examples: n Underground experiment n X-ray fluorescence -Major new features: digitisation, ntuples -New analysis design -Will be released with UR, designs, traceability Status: will be tagged by 30 November Testing -Many new unit tests -Unit testing  AIDA/Anaphe Status: implemented, tested, tagged Migrations -STL, “new” materials etc. -ANSI strict options -Cuts per material (aka tracking media) Status: all implemented, tested, tagged (“cuts per material” not supported)

2. Maria Grazia Pia, INFN Genova - G4 WG Coord. Meeting, 13/11/2001 We have never documented a design of our examples… This class diagram triggered a lot of reverse engineering

3. Maria Grazia Pia, INFN Genova - G4 WG Coord. Meeting, 13/11/2001 Reverse engineered No design existing G4ANALYSIS_BUILD G4ANALYSIS_BUILD_LAB G4ANALYSIS_LAB_VISUALIZATION G4ANALYSIS_BUILD_LIZARD G4ANALYSIS_BUILD_JAS G4ANALYSIS_NON_AIDA AIDA_DONT_USE_STD G4ANALYSIS_USE G4ANALYSIS_USE_LIZARD G4ANALYSIS_USE_LAB G4ANALYSIS_USE_JAS (confusing for users…) A lot of environment variables required Current content of the Geant4 analysis directory

4. Maria Grazia Pia, INFN Genova - G4 WG Coord. Meeting, 13/11/2001 New, simpler design Will be implemented in the advanced examples for the release More general and elegant, but still simple, design under discussion No environment variables needed or HistogramManager

5. Maria Grazia Pia, INFN Genova - G4 WG Coord. Meeting, 13/11/2001 emlowen-V03-02-44 Also allows plotting histograms while running the simulation (UR) New design already implemented and tested structural prototype

6. Maria Grazia Pia, INFN Genova - G4 WG Coord. Meeting, 13/11/2001 already done still to be done Major role of analysis internal to Geant4 Use cases, OOAD, code, traceability in CVS repositories

7. Maria Grazia Pia, INFN Genova - G4 WG Coord. Meeting, 13/11/2001 Work already started… emlowen-V03-02-42 exploratory, evolutionary prototype

8. Maria Grazia Pia, INFN Genova - G4 WG Coord. Meeting, 13/11/2001 Workers Henrique Araujo (UCL, London) Riccardo Giannitrapani (Udine) Elena Guardincerri (Genova, student) Susanna Guatelli (Genova, student) Alex Howard (IC, London) Francesco Longo (Ferrara) Ramon Nartallo (ESA) Andreas Pfeiffer (CERN) MG Pia (Genova) Giovanni Santin (Trieste) Everybody is welcome to join the effort, of course! (…there is plenty of work to do…) Collaboration with Physics and Testing WGs especially desirable Contributions to Use Cases would be very helpful (10 people, from 8 institutes)

9. Maria Grazia Pia, INFN Genova - G4 WG Coord. Meeting, 13/11/2001 Conclusions The major role of analysis in Geant4 is internal -Physics -Unit testing -System testing External role only to facilitate the user support process (examples) A lot of work has been in progress for ~1.5 years -both in the external and internal domain -several people actively involved Rigorous software process adopted -to generate a high quality product Various artifacts already available Note 1: Let’s not confuse the work for analysis in Geant4 with the development of AIDA or of any specific analysis system Note 2: A liaison with AIDA, CLHEP, external products would be useful
