Issues

• Running with FFB off
• Removed BPM Y burp cuts (again, retroactively)
• BPM 12X (and all monitors) see regular short spikes (still) - it seems to be getting worse

• BPM Noise issues
  • BPM 12X jumps are hard to cut - Robert is working on a 12X burp cut estimate for that
  • BPM Y has noise when burp cut is off, but it doesn't seem to negatively impact asymmetry or detector yields, and is smaller than target size
  • BPM Y burp cut ON kills BMOD coil 6

Updates

• BMOD tune seems OK.
