Experimental Data Locations

Run Group C, 2022-23

  • /group/poltar/HallB/RGC
    • Proton data in directory data-p
    • Deuteron data in directory data-d

SANE, 2009

  • /group/poltar/HallC/SANE
    • all_data.csv contains NMR system meta-data
    • epics_export.txt contains EPICS meta-data
    • events folder contains online data with raw NMR signals
    • Several ipynb files give examples of reading the above files

EG4, 2006

  • /group/poltar/HallB/EG4/eg4_nmr_clean
    • Data is in binary format. I'll provide a script to convert to text.

List of observed photon beam coherent peak shifts to take a look at

  • March 30 2018 - before and after the repositioning of the diamond.
  • before March 30, last run before the beam went down and first run after it came back, unless Hovanes realigned
  • https://logbooks.jlab.org/entry/3761564 - look at difference between reference and observed peak
  • CPP - several instances of wild beam energy shifts reported NB nominal position was around 6 GeV not 9 GeV
  • Demon's plots show a variety of interesting coherent peak positions near the start of 2017
  • logbook entry Cristiano nudged 6-25-22 00:39 run 100667
  • logbook entry Naomi nudged Jan 17 2018 run ?
  • logbook example of bad fit in the expert? part of the gui
  • logbook nudged the diamond after switching to perp, and then the fit was having issues (because of a bad uscope channel, I think)

Shopping list

  • date
  • run number
  • radiator id
  • goniometer angles
  • e beam position & current
  • coherent edge position and width. It looked like the width changed abruptly in the March 30 incident.
  • PS scalers
  • TAGM & H scalers
  • How stable is the PS acceptance, does the PS E histogram from AMO runs change with time?
  • Does the PS E histo change between one storing of the TAGM AMO reference and the next?


  • myaplot config files and plots for some of the above (edge & width), (edge & width & beam position)
