Finishing up looking at BPM issues and Aq issues

  • 7790-7794 run range has a BPM Y hairy noise that is in all BPMs
    • Check if the beam trip recovery is at fault
    • If needed add a Y hard limit cut to some of these runs (maybe 4eY)

February 2nd 2021

BPM 1X and 12X look stable and have reasonable noise, coming from Devika's analysis of BPMs vs. eachother.

Looking at 12X and Target BPM jumps/shift runs: http://ace.phys.virginia.edu/HAPPEX/4428

  • BPM Target matter for avoiding copper
  • BPM E matter for avoiding inelastics and preserving regression stability

Need to finish looking at BPM jumps on Friday

February 1st 2021

Finish looking over runs:

  • Finished looking at NeedCut and Suspicious runs - suggestions live in spreadsheet
  • Pedestals for BPMs are all over the place, and cause yield shifts
    • These yield shifts bump into limit-cuts for target BPMs at least once, and likely more - see HAPLOG 4454
    • BPM 12X sees a 0.3mm shift during CREX part 2 vs. it's prompt value, this likely causes cut issues too
    • Reverify pedestal values used in respin1
    • Recheck pedestal analyses for quality

We looked at the run lists generated by WACs over the last few weeks and blessed suggestions or suggested new things to do to fix runs with obvious issues or solutions:

We'll meet again on Monday (starting at 7994 in the NeedCut list) and also look at the BPM jump run list (http://ace.phys.virginia.edu/HAPPEX/4437)

January 26th 2021

Last day of going over issues and populating the WAC lists. A number of comments and notes are listed here, including possible merging of slugs, etc.
