This is a summary page with the progress of the PionLT experiment. Above is a quick outline of our current progress. Below are tasks assigned to members of the group. Anyone who is part of the group may contribute to a task with suggestions and/or updates on progress. Please contact the assignee on a task-by-task basis for any queries. Anyone with general questions can contact Jacob Murphy (), Muhammad Junaid () and Nathan Heinrich ().

Completed Tasks

Detector Calibrations Completed

  • Kinematic Check Done
    • Ensure Kinematics are correctly labeled in the analysis
      • Check 2021 Kinematic Settings
      • Check 2021 Offsets (still needs to be checked)
      • Check 2022 Kinematic Settings
      • Check 2022 Offsets (still needs to be checked)
  • Per Peter Bosted's suggestion, look at ELCLEAN and BCM scalars (in report file) and determine stability (can also check previous run periods)
    • Good way to determine runs with issues as the ratio should be constant with current/rate
  • Timing Cuts
    • Nathan
    • ADC/TDC timing windows should be checked/applied for all run periods
  • HMS+SHMS DC (Junaid)
    • Carlos worked on this analysis, finding drift times card-by-card
    • Completed
  • HGCer (Nathan)
    • Find SPE peak (low event run)
    • Completed
  • NGCer (Nathan)
    • No SPE peak to find
    • Check width of peak (high event run)
      • width is root n of mean value
    • Script is available (Cameron C. did it for XEM 2)
    • Completed
  • HMS Cer (Nathan)
    • Find the SPE peak
    • Completed
  • Aerogel (Nathan)
    • Completed
  • HMS+SHMS Hodoscope (Jacob, Junaid, Nathan)
    • Dave Mack/Carlos Yero/Jacob
    • 2021 SHMS calibrations in good shape
    • 2021 HMS calibrations should be double-checked
    • 2022 HMS and SHMS calibrations should ideally be done with defocused and maintained throughout the run period
    • Did recalibrations because files were missing.
    • Finished Timewalk Calibrations. (Nathan)
    • Finished VpCalib Calibrations. (Junaid)
    • Completed

Tracking Efficiency Studies Completed

  • Tracking Efficiency Studies (Junaid)
    • Updated DEF file (Included NGC variables)
    • Updated DEF-Cut files for HeeP, Lumi, Prod and pTRIG6 data.
    • Done Setting up Report files.
    • Generated BCM currents for PionLT data.
    • Done Setting up replay scripts.
    • Updated efficiency study scripts (including CSV file generation script and plotting script)
    • Completed
