GEOM 180313¶

Monday 18 March at 15.00 GMT

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

Proposed date of next meeting Friday 5th April time t.b.c. (Ryan at RAL, Jason on holiday) -

Actions from Previous Meeting¶

• ACTION: Jason to provide CAD files with fixed orientation and less details
  • STANDS
• 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.
  • TO BE REDONE with new CAD files
• ACTION: DISCUSS ID/time-stamp of MC ideal geometry
  • DECISION use a time-stamp in the past,e.g., Year 1974 of ideal STEP IV, 1975 for ideal Step V, etc.
• 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 orientation problems to be fixed
• 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
• ACTION: FIX tracker GDML files - problem in translation (Ryan)
  • NEW
• 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
• ACTION: Invite Gene Kafka to report on Cherenkov geometry(Stefania)
  • POSTPONED

Notes¶

Problems foudn with first CAD files with correct orientation, wrong material, extra modules. Problem related to FASTRad conversion to GDML
Matt may shed some light on it. If not, haev to revisit conversion from STEP->GDML->MICEMODULE->GEANT
Chris R. can skip either GDML conversion or internal MAUS Format, as Geant accepts GDML as input.

Discussion on Surveuy procedure: every time there is a new Survey, new CAD fiels will be produced and an entire new Geometry will be uploaded to CDB. Discussed opportunity to checke differences with previous geometry.

Present:¶

Ryan, Chris R., Jason, stefania

Actions¶

• 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 but 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
• ACTION: Invite Gene Kafka to report on Cherenkov geometry(Stefania)
