Discussion Items from previous meetings¶

• Survey - EMR was surveyed last week. Jason has information also about Cherenkov survey, which he will pass on to Lucien.
• Integration survey CAD. Jason has provided a CAD model with TOF0,1 position according to January 2013 survey and TOF2 according to October 2013 survey. Ryan is developping a fitter which will take in input the sphere position, information from TOF responsible of the relative position between the survey points and the center of detector, to place the center of the TOF in MAUS. This procedure will be repeated for EMR and any other detector which will be surveyed at the end of the run, then a new geometry will be uploaded to CDB backdated at October 4th, when EMR was installed in the MICE hall. Aiming to have something running for a production test in January. An important point which emerged today is that information from detector experts on relation between survey points and center of their detector should also be stored in CDB. In addition, each time a geometry is uploaded in the CDB, information in the comment field should be provided to describe what is that particular geometry for (which CAD design, which detectors have been placed according to which survey, which have been placed according to which alignment). Format to be coded.
• Magnetic fields (currents from CDB to MAUS Modules).
  Currents are not in CDB yet, but infrastructure exist to read them from there once Run Control writes them. For the time being we use hard wired currents.
• EMR description (preliminary code shown by Ruslan, to be cleaned-up) and relation Survey points to first detector plane
  • http://bazaar.launchpad.net/~maus-emr/maus/devel/files/head:/src/common_cpp/DetModel/EMR/
• cherenkov and KL descriptions (will be legacy files) - Maryan KL description is probably too detailed. Lucien - a IIT student may work on updating Cherenkov geometry (material budget only? probably not photon tracing)
• Discussion on the survey of the DSA wall and all beamline elements (Henry) - Beamstop partially obstrudes hole even if open (in QUAD acceptance?)
• Progress on RF cavity description - rotation asymmetries, need to describe cavity tuner material (Jason)

Standing Actions¶

• ACTION translate TOF (from legacy files updated by Durga) to gdml and store to DB (Ryan)
  • STANDS - translation in progress (Pending store to DB)
• ACTION: Integrate Absorber (MAUS Modules) by Pavel in new geometry and store to DB (Ryan)
  • STANDS- integrated legacy files with new model for absorber, but not yet in DB
• ACTION: FIX tracker GDML files - problem in translation to MAUS Modules (Ryan and Chris H.)
  • DONE - independently by Chris and Ryan
• ACTION: Improving TRACKER Geometry description - fibres outside fiducial region (Heidt)
  • STANDS
• ACTION: Victoria Blackmore to implement magnet field map interface (Victoria)
  • STANDS
• ACTION: Check performance of fit on Cherenkov survey information
  • STANDS - Too large rotation (lack of redundancy?)
• ACTION: Ruslan to provide relation between survey points and centre (?) first EMR plane
  • STANDS
• ACTION: Ruslan to release EMR geometry for MAUS release
  • STANDS
• ACTION: RYAN to provide interface to fit for best detector positions, given survey points, to place all volumes.
