260 Hz Vertical Oscillation Ocurring between 7A04 and 8E01
Today I discovered FastSEE BPM light mode will let you select pass while still in auto select! that means all of these waveforms are available without disrupting any lock operations. Any oscillation up to 3.5 KHz can be localized to an Arc.
Wonderful news aside, A magnet seems to be shaking between IPM7A04 and IPM8E01 at 265 Hz vertically in an intermittent fashion. No suspected magnets yet.
Hall C Raster B X current is noisy

07/28/2026 BPM Maintenance/Work:
IPM1A08 and IPM2A08 LabJacks are installed and awaiting Software configuration
IPM2A16, IPM4,6,8,A13 BPM Stack's Troubleshoot - Found the system to be reporting well within 100 microns of position reproducibility with strong ADC counts and balanced X&Y Gain values when utilizing onboard testing. Will continue to monitor this BPM stack's position performance.
