Discussion Items from previous meetings

  • What is missing to provide simulation for the October STEP1 EMR run?
    • CAD model of EMR run. This now exists, and has been uploaded to CDB. Survey will be performed at the end of the run.
    • Integration survey CAD. Jason has provided a CAD model with TOF0,1 position according to January survey and TOF2 according to October surevy. Ryan will develop 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 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. However, in the last meeting it was discussed to not upload the fit corrections to CDB, which will then become MAUS version dependent and will have to run evrytime before calibration. To be discussed again.
    • 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
    • cherenkov and KL descriptions (will be legacy files) - Maryan KL description is probably too detailed.
    • Discussion on the survey of the DSA wall and all beamline elements (Henry) - Beamstop partially obstrudes hole even if open (in QUAD acceptance?)
    • Discussion on geeting code to a MAUS release (tests being runned by Durga)

Actions

  • ACTION: Ryan to upload latest 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. Proton absorbers?
    • DONE (proton absorber is before D2, hence it is not needed)
  • ACTION: Stefania to compile and verify Ryan's developer version
    • DONE (first time tests and validation to be shown at Collaboration Meeting)
  • ACTION translate TOF (from legacy files updated by Durga) to gdml and store to DB (Ryan)
    • STANDS - integrated legacy geometries for TOF, translation to GDML regarded low priority but will be done
  • 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.)
    • STANDS
  • ACTION: Improving TRACKER Geometry description - fibres outside fiducial region (Heidt)
    • STANDS
  • ACTION: Victoria Blackmore to implement magnet field map interface (Victoria)
    • STANDS
  • ACTION: Integration of survey and geometry, all TOFs and Cherenkovs have now been surveyed. Propagate the survey info to CAD/DB (Jason/Ryan)
    • DONE/STANDS
  • ACTION: Ruslan to provide relation between survey points and centre (?) first EMR plane
    • STANDS
  • ACTION: Rusaln to release EMR geometry for MAUS release
    • NEW
  • ACTION: RYAN to provide interface to fit for best detector positions, given survey points, to place all volumes.
    • STANDS
