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)
• logbook 27 Jan 2018 Simon had trouble nudging the diamond, hit the button but nothing happened, found that the microscope scaler display was not updating
• logbook 15 Aug 2022 Simon & Joerg corrected edge position for 101600
• logbook Simon, 25 Jan 2018
• logbook Simon, 10 Feb 2018 (only the 'after' pic but he said he moved it 70MeV)

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)
