October 23th 2019

Daily Meeting BlueJeans

Agenda

Lets follow up on Tao's summarized spreadsheet https://docs.google.com/spreadsheets/u/1/d/1Y6qR_h4oW4qNmbtdpo2TIX2u_TI5qjRUZIDyEroMfl0/edit#gid=0

Issues Done

  • A bunch of runs from the spreadsheet have been investigated
  • Some tools for investigating runs have been developed by Tao and others (in various repositories, should be joined into JAPAN soon)

Issues Pending

  • Update slugs with accurate RCDB/disagreements - https://docs.google.com/spreadsheets/u/1/d/1Y6qR_h4oW4qNmbtdpo2TIX2u_TI5qjRUZIDyEroMfl0/edit#gid=0
    • Some mis-labelled runs
    • Some runs with NeedsCuts should be addressed at next week's meeting - put your suggestions into the spreadsheet
    • Some runs have disagreeing RCDB/slow tree EPICs data - this needs to be checked carefully and have the Blinder state forced in a separate map
  • Aq failure/large charge asymmetry solution:
    • We should check the pockels cell voltages to see if Aq was trying to be on/when it turns on
    • We should look at the feedback log during these runs to see if it was updating
    • If no Aq feedback running then probably ignore the run
    • Otherwise check when Aq feedback turns back on and see in a prof plot once it converges (by eye) in order to begin accepting data
    • We should check all "bad" run comments to see if they were marked as bad due to Aq failure and re-consider them
    • Weibin will go and look at Aq feedback logs to get this information at first order -> run list

Planned Updates

Pedestals

  • Devi has made log entries on this:
    • We should look at all of the calibration runs/condition changes and make sure that the pedestals calculated accurately reflect the conditions during that time
    • We should make sure that all pedestal changes are well motivated and no calibration runs were neglected
    • We should make sure that early runs aren't missing pedestals that may currently have later run ranges (Due to late application)
  • Robert has made a log entry on identifying pedestal changes across runs http://ace.phys.virginia.edu/HAPPEX/3917

BCM normalizer, systematic control, etc.

  • Cameron has reproduced Catherine's BCM systematics vs. normalizer/Aq BCM, but now with DDs in it too - this lives in a parallel folder to the main slug plots (called PQB)
  • Victoria and W&M students are running with this and making diagnostics about systematic control on Aq
  • Devaki has revisited up-to-date JAPAN operations map files, made summary list of normalizing BCM in run list and compared conclusion from different sources. http://ace.phys.virginia.edu/HAPPEX/3915

Including Dithering as Production Data

  • Victoria will use cuts to investigate how it looks to include the dithering data (that was cut before) as production data
