Minutes

Attendees: Naomi J., Torri J., Nikhil K., Thomas B., Kishan R., Mike G., David L.

• Diana's Document on Gain Correction Factor
  • Not enough people read it. Assign as action item for next week
  • Diana identified a couple of more items to add

• Why is 2018 data so bad?
  • Naomi thought about some possibilities
    • Beam trips were much worse
    • Diamond was worse (Alex A. reported strong dependence on orientation)
    • Beam tune (at one point better agreement between orientations noticed after high-quality beam tune)
  • How to address
    • Naomi suggested we focus on using the CDC HV board currents instead of external beam parameters.
    • Some concern over how much time to spend on reproducing GCF for 2018 data as it prevents us from moving towards the final goals of the project.

• Good File List (Nikhil)
  • Nikhil was able to produce a list of runs for which the 001 file (the one used for calibrations) was "good" (i.e. no beam trips)
  • System scrapes data from CCDB utilities.
    • It was noted that there is a python API for CCDB. This was not pointed out to Nikhil earlier, but he now has a working system so we go with that.
    • Run the system over the 000 and 002 files from 2018 so we can identify if which runs have at least one "good" file amongst the first 3

• PrimEx Run Plan
  • CDC is expected to be turned on about 9.5 days from now (n.b. that schedule has since changed)
  • Expect 16 shifts with beam on (4 days)
  • One of us will need to sit in as additional remote shifter to handle determining the HV setting and implementing it between runs
  • We will need to set up a schedule for which of us will be online
    • Thomas, Naomi, Torri, and David will likely be the ones implementing this.
    • We will set up internal training

• Time to Distance Calibration
  • No progress this last week

• CLAS12 (Torri)
  • Trying to get a good run list. Not clear how to obtain this
  • Able to produce Trees now
  • Setup a GitHub page listing projects
    • Need to add everyone's Github account to it

Action Items

1. Read the Gain Correction Factor Status Document (Everyone)
2. Check for "good" runs in the first 3 files (0,1,2) of the 2018 data (Nikhil, Torri)
3. Schedule for who from our group will be on shift to change HV settings
   • Plans (Naomi's slides)
   • PrimEx Run Plan
4. Add everyone's Github account to the Github AIEC Projects page (Torri)
