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).

h2. +Completed Tasks+

h3. Detector Calibrations **%{background:lightgreen}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
