  • CDC
    1. In progress (Naomi). Start incorporating new PrimEx 2022 data. Naomi will get gcfs, Diana will get epics w Thomas's help.
    2. Scale 2018 gains up (gcf down) by the improved "6%" & add to the model. See docdb
    3. Separate the EPICS readings & rethink the averaging times.
      • Use the wait and see approach for the HVB current - a few seconds of beam-on time is probably good enough. Wait 3s, read 3s. Prestart is taking about 43 seconds these days. Do we have time to wait 12 secs, read 3-5 secs?
      • Use a longer lookback for the temperature, because the readout is coarse and the value is important for the UQ. Use the mean instead of the max. 5 minutes.
      • Consider what to use for pressure. 5 minutes.
      • Beam current after trips
    4. Move the EPICS reading + HV setting to Prestart.
    5. Make the EPICS reading + HV setting as fast as we can; possibly coordinate w Alex to use monitoring files that miss the time before the HV is set.
    6. In progress (Diana) Set up a standard series of tests for the raw gcfs from a new model, and also for the UQ corrected data. Start with a book of plots and possibly automate looking through the book.
    7. Done (was done all along, 2021) Make sure that the initialization is scaling the gcf to its mean pressure equivalent, if it is not doing that already. So far all the inits have been done at mean pressure or close to it.
    8. Done (Naomi - closer to 3% Sept 2022) Look more closely to find what the 6% correction should be. See if we can match beam current & radiator (ideally amo) & pressure.
    9. Done (Thomas) - switching to data-collection outside the 3% confidence bubble. Discuss an option for "this is it" or "get more data", when to use auto-off and should there be an auto-on.
    10. Done, unseen (Diana) Plot predicted std dev from the model vs the difference between predicted and traditional gcfs.
    11. Done (Thomas/Diana) Re-enable the HVB current.
    12. Done (Thomas/Torri, 11 Oct) - keep RoboCDC running but recommend 2125 for non-full-target runs. ie auto-collect for ET.
  • FDC - correlation between gcf & pressure was good for 2020, inconsistent for 2018. Torri needs to talk to Lubomir.
  • BCAL - baselines and crate temperatures. Need an executive status summary.
  • Other detectors - for capstone students.
    1. first start w sqlite & ccdb api & ccdb table description spreadsheet & maybe some epics
    2. FCal, BCal & TOF??
    3. David think about adding fadc temps to sync events, maybe hoss skimming them, maybe more syncs than at present.
    4. Done (Naomi) Make a list of useful calibration tables & detectors. Ask the experts. CCDB EPICS
