24 June at 15.00 BST

  • Geometry (Ryan Bayes)
  • Geometry Verification (Stefania Ricciardi)
  • Absorbers (Pavel Snopok)
  • CAD Models (Jason Tarrant)
  • Detector Groups: Tracker (Chris Heidt?)
  • Magnets (Victoria Blackmore, others?)
  • AOB

Discussion Items from Previous (i.e. Collaboration) Meetings

  • What are the priorities for geometry development?
  • How do we include the survey information?
  • Does the list of members need to be redefined?
  • How does (should) the MAUS geometry interact with the g4beamline geometry?

Actions from Previous Meeting

  • Jason - to refine CAD models in beam acceptance region (He windows, flanges, etc..)
    • STANDS
  • Ryan - solve problen in traslation GDML->MAUS Modules
    • DONE further optimization may be needed
  • 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), DIFFUSER (CAD files from Jason) geometry to gdml and store to DB (Ryan)
    • STANDS - integrated legacy geometries, but positioning of TRACKERS, DIFFUSER, and ABSORBERS still needed
  • ACTION: Integrate Absorber (MAUS Modules) by Pavel in new geometry and store to DB (Ryan)
    • NEW
  • ACTION: FIX tracker GDML files - problem in translation to MAUS Modules (Ryan and Chris H.)
    • STANDS
  • ACTION: Improving TRACKER Geometry description - fibres outside fiducial region (Heidt)
    • STANDS
  • ACTION: GEANT4 warning messages when geometry from CAD import is used (Ryan)
    • DONE - removed from upgrade to g4.9.5
  • 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

Chris Rogers Notes

  • Wrap up from CM
    • Maria Leonova is in charge of G4BL
    • Likely that we will not get running in June 2014, hence magnetic fields should have higher priority than tracker
  • Survey and geometry
    • There was some discussion on survey, clarified below
    • Engineering elements integration
      • Jason to get survey points from surveyor
      • Jason to provide CAD drawing for each "engineering" element with survey points marked on it
      • Jason places engineering CAD in overall survey
    • Physics elements integration (e.g. detectors)
      • Jason to get survey points from surveyor
      • Detector group is responsible for providing data on relationship of sensitive detectors to survey points
      • Where detectors are overconstrained, Ryan is to provide code which makes a best fit and throws an exception if the fit is out-of-range
        • Presumably physics group is responsible for providing data on fit range (i.e. SciFi maybe wants ~ 500 microns; TOF maybe wants ~ 1 mm; ckov wants ~ 1 cm... etc)
      • Ryan is to define MiceModule/GDML schema to which detector groups should interface
  • G4BL job
    • Two sample use cases were identified
      1. User wants to run G4BL on his laptop (and possibly interface directly to MAUS)
      2. User wants to pull down a pre-existing data set from e.g. config db and interface with MAUS
    • Propose writing a MAUS mapper that takes empty spills and fills with dataset
    • Then make three different executables, in the spirit of bin/simulate_mice.py
      • An exe that uses MapPyBeamMaker to generate an input from a g4bl "beam" file and fires the rest of the MC
      • An exe that fires g4bl and does nothing
      • An exe that fires g4bl, brings g4bl into the full MC and then goes from there.
