Slug 9/10

Start Slug 9 on 3520, junk until 3522

Calibration - 3523: Aggressive Aq scan
Calibration/Needs Cuts - 3524: IA scan
Good - 3525: begin production proper
Good - 3526
Good - 3527
Good - 3528
Good - 3529
Good - 3530: first 30k events have a beam excursion, this begins a 4 run long beam motion problem that affects the position locks/energy lock (due to FFB being off apparently - see HALOG)
Good - 3531
Good - 3532: Noticeable 12 X beam trip recovery issues
Good - 3533: Halog - End of the long BPM 12 X wandering journey that changed regression slopes
Good - 3534: Back to normal
Good - 3535
Good - 3536
Good - 3537
Good - 3538: Trippy beam... OK
Good - 3539
Good - 3540: BPM movement... OK
Good - 3541

Start Slug 10 on 3542, junk 3542

Junk - 3542: start of slug, empty
Good - 3543
Junk - 3544: BPM saturation
Good - 3545: BPM saturation resolved
Good - 3546
Good - 3547
Good - 3548: beam movement
Good - 3549: beam movement
Good - 3550
Good - 3551
Good - 3552
Good - 3553: Watch out - very short
Good - 3554
Good - 3555: To mitigate beam movement - Perpetually on FFB now - looks good, other than broader BPM Y widths and 4eX looks noisier than its complement
Good - 3556
Good - 3557: Double peaked BCMs - 250-300 ppm widths, 0.4 ppm mean Aq
Good - 3558: "" , 0.1 ppm mean Aq
Good - 3559: BCM still wide
Good - 3560: 220 ppm Aq width, 0.4 mean Aq, one bad spike in BCM too that wasn't cut out
Good - 3561
Good - 3562
Good - 3563: bcm looks good again now
