Monday 28 January at 15.00 GMT

• Geometry (Matt Littlefield)
• Geometry Verification (S Ricciardi)
• Absorbers (P Snopok)
• CAD Models (J Tarrant)
• Detector Groups: Tracker (C. Heidt)
• Magnets (Victoria Blackmore)
• AOB

Proposed date of next meeting Monday 11th January at 3pm GMT -

Actions from Previous Meeting¶

• ACTION: produce ideal STEP IV geometry(Jason)
  • DONE
• ACTION: Matt 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.
  • IN PROGRESS
• ACTION: Discuss ID/time-stamp of MC ideal geometries with Anthony W.(Stefania)
  • DECISION use a time-stamp in the past,e.g., Year 1974 of ideal STEP IV, 1975 for ideal Step V, etc.
  • 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)
  • WAITING for CAD model to be made available in MAUS release
• ACTION: Store all tracker geometry in CDB (Chris->Matt->Ryan)
  • IN PROGRESS. Chris has written gdml description. Matt has produced a transfer script. Ryan will familiarise with the system and upload to CDB.
  • STANDS Chris to remove diffuser supports and SOLENOID from tracker geometry description as it will be simulated by CAD
• ACTION: Improving TRACKER Geometry description - fibres outside fiducial region (Heidt)
  • STANDS (postponed to January)
• ACTION: GEANT4 warning messages when geometry from CAD import is used (Ryan and Matt)
  • STANDS
• ACTION: Produce geometry documentation for code developpers and pass information to Ryan (Matt)
  • IN PROGRESS
• ACTION: Victoria Blackmore to implement magnet field map interface (Victoria)
  • STANDS
• ACTION: Invite Gene Kafka to report on Cherenkov geometry(Stefania)
  • STANDS

Notes¶

Matt and Ryan in Glasgow are working on producing an ideal STEPIV geometry, including tracker and TOF. It will be available in the CDB by the end of the week.

Henry raise some questions related to the survey measurements: how should they be interpreted (centre of the ball or back of the socket)? How do they relate to the detector position and to the official MAUS reference system? What is actually done to translate them into the CAD model? Which period of time so they refer to? Are cross-checkes necesary? Documentation requested.
