Non-Production Runs and Bad Runs

Scans:

Issues

  • FFB issues again - to mitigate BPM Y noise and possible major regression/BMOD analysis singularity: Turn of FFB and run with the BPMs free
  • JAPAN Regression appears to be singular while FFB is off, but not during the unser scan on carbon 1% target with FFB OFF! - Paul determines this to be non-fatal and we can proceed, JAPAN has had a code base update to avoid this failure going forward.
  • BMOD is all over the place, FFB is all over the place. I am starting to do 4aX and 1X with Coil 3 or 5, all 4 analyses
  • We are getting daily sync check errors... see Run 7728 https://logbooks.jlab.org/entry/3827533
