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 (jm443918@ohio.edu), Muhammad Junaid (mjo147@uregina.org) and Nathan Heinrich (heinricn@uregina.ca).

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

• Calorimeter (Junaid)
  • Use defocused run (With the correct optical matrix, https://logbooks.jlab.org/entry/4050240)
  • 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
