Agenda

  1. Announcements
  2. Summer installation planning:
    • Window for upper box (Ernie)
    • Plans for tests with LED fibers and canullas (Bill/Fernando)
    • Plans for making bar boxes light tight (All)
  3. Spring 2019 DIRC Commissioning (All)
    • REST file processing (ver08) just completed for all commissioning runs with beam 60700-60883:
      • /cache/halld/detectors/DIRC/RunPeriod-2019-01/dirc_monitoring/ver08/REST/
    • Initial pass over REST with plugins in progress to make ROOT TTrees for further analysis: dirc_reactions,dirc_tree,ReactionFilter
      • /volatile/halld/home/gxproj7/RunPeriod-2019-01/dirc_monitoring/analysis_REST/ver08/
    • LUT comparisons (files are located at /group/halld/Users/jrsteven/2018-dirc/):
      • lut_commissioning_2019_v10.root, (default) what's in CCDB with the “nominal” geometry and photons generated over the full end of the bar surface
      • lut_commissioning_2019_v12.root, Yunjie’s “as-built” geometry with photons generated over the full end of the bar surface
      • lut_commissioning_2019_v13.root, Yunjie’s “as-built” geometry with photons generated from the center of the bar end only (ie. DIRCLUTSPREAD=0)
    • LED data analysis and comparison to laser test stand data Plots (Bill/Andrew)
  4. Software/simulations
    • Realistic efficiency/time resolution implemented in DIRCSmearer and merging with random hits added: current branch on GitHub (Justin)
      • Simulation samples for ρ, φ, and bggen available at /volatile/halld/home/jrsteven/2018-dirc/dircsim-2018_08-ver15/
      • Will submit pull requests for hdgeant4 and mcsmear to include bar-dependent photon yield (see next)
    • Bar-dependent photon yield (Justin, All)
    • Finalizing DIRC "as-built" geometry: JT model from survey/alignment (Yunjie/Stephanie)
    • Adding # photons to LUT likelihood (Maria)
    • FastDIRC geometry implementation and alignment work (Cris/Yunjie)
  5. Software overview and tasks (All)
  6. AOB
