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).

Ongoing¶

Expected to be completed in the start of July, 2023

Calibrations In Progress¶

• Kinematic Check
  • Jacob
  • Ensure Kinematics are correctly labeled in analysis
    • Check 2021 Kinematic Settings
    • Check 2021 Offsets
    • Check 2022 Kinematic Settings
    • Check 2022 Offsets

• 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
  • Jacob
  • ADC/TDC timing windows should be checked/applied for all run periods

• HMS+SHMS DC (Junaid)
  • In Progress
  • Carlos worked on this analysis, finding drift times card-by-card

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

• HGCer (Nathan)
  • In Progress
  • Find SPE peak (low event run)

• 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)

• HMS Cer (Nathan)
  • In Progress
  • Find the SPE peak

• Aerogel (Nathan)
  • Completed

• HMS+SHMS Hodoscope (Jacob)
  • 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 maintain throughout the run period

• Saturation Corrections to Optical Matrices
  • Jacob
  • HMS 6.6 GeV
    • Carbon-Sieve
