  • Geometry Verification (Stefania Ricciardi)
  • Absorbers (Pavel Snopok)
  • CAD Models (Jason Tarrant)
  • Detector Groups: Tracker (Chris Heidt)
  • Magnets (Victoria Blackmore)

Proposed date of next meeting Tuesday 30th April time 3 pm -

Actions from Previous Meeting

  • ACTION: Jason to provide CAD files with fixed orientation and less details
    • DONE but problem with FastRad conversion to GDML (extra modules, all materal is Al)
  • ACTION: Ryan to upload Jason's CAD model to DB to have a first version of STEP IV geometry in a MAUS release.
    Diffuser and cooling channel in two separate CAD files to be merged.
    • STANDS
  • ACTION: Stefania to check how much time/particle/s with CAD geometry on RAL Tier2 (Matt reports 2.8 s/particle on his laptop)
    • STANDS Stefania checked that legacy files give 2.7s/muon with STEP IV on TIER2 PPD machines
  • ACTION translate TOF (from legacy files updated by Durga), ABSORBER (Pavel), DIFFUSER (CAD files from Jason) geometry to gdml and store to DB (Ryan)
    • Ryan working on TOF, to be tested
  • ACTION: FIX tracker GDML files - problem in translation (Ryan)
    • STANDS
  • ACTION: Improving TRACKER Geometry description - fibres outside fiducial region (Heidt)
    • STANDS
  • ACTION: GEANT4 warning messages when geometry from CAD import is used (Ryan)
    • STANDS
  • ACTION: Produce geometry documentation for code developers and pass information to Ryan (Matt)
    • IN PROGRESS
  • ACTION: Victoria Blackmore to implement magnet field map interface (Victoria)
    • STANDS

Notes

Jason looking into simplyfing other parts of the CAD model, but feedback needed.
Material issues (all components Al) could be due to Fast RAD interface. Ryan and Jason to check out GDML and IGES respectively to narrow down where the problem is.
Ryan will try to use the IGES files sent by Jason and produce new simulation files and see whether extra-elements have been added. Option with no GDML to MAUS Module interface ("revolutionary approach") set aside for thoughts in the background. Priority is to fix current simulation approach.

Present:

Jason, John, Ryan and Stefania
