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 Christiano nudged 6-25-22 00:39 run 100667
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)
