Things we did not get to, but that we may want to discuss at some future beamline meeting include the following.

  1. The rate difference with different diamond orientations (entries 3456227, 3457757, 3457790)
  2. The beam energy for this run (latest entry: 3457959). Also the BEM fix (scheduled for Thu. 21st) and its recent failures (entries 3456851, 3457107).
  3. Soft photon background (induce satellite peaks on profiler and the rate difference with different diamond orientations).
  4. System failures (PS power supply, target IOC).
