Production Run List

Start Slug 14, IHWP In, FFB on always

• • Since we are using bcm_dg_ds, the width in the bcm asymmetry is 2X of what we had with bcm_an_ds
  • We used the same, bcm_dg_ds, bcm in slug13 also, where the Aq width was ~1.5X of what we had with bcm_an_ds
  • SAM3 started saturating since run3640
  • Should we think about changing saturation limit for this SAM?
  • If we compare with 70uA good run from previous slug, yield of SAMs on Right Hand Side has increased while on the other side decreased
• Good - run3649
  • Short run with many beam trips
  • Caryn says "attempting to go to production but having some FFB issues"
• Good - run3651
  • BPM11 has saturated couple of times
• Good - run3652
• Good - run3653
• Good - run3654
• Good - run3655
• Good - run3656
• Good - run3657
• Good - run3658
• Good - run3659
• Good - run3664
  • Regressed detector widths are ~5ppm higher than previous runs->might be due to the jump in current from 70uA to 60uA
• Good - run3666
  • mini-run 8 had too large widths in regressed detector asymmetry
  • Quad problem, applied cut->Looks good

Non-Production Runs and Bad Runs

• Test run3637
• Test run3638
• Test run3639
• Test run3642
• Test run3643
  • Musson injects 10uA fake signal into digital system after new chassis added
  • All the runs upto here were under slug13 conditions
• Test run3644
  • Target Trouble Shooting
• Test run3647
  • Beam current ~20uA. No event passed event cuts.
• Bad run3648
  • Attempting to production but some Feedback issue
  • Quite big Aq mean, very short run ~11k events
  • Only 4k events have passed event cuts
• No Beam - run3665
• Test - run3667
• Test - run3668

Pedestal/Calibrations Updates

• Current Calibration run3645
  • New target (D9PbD10)
• PITA Scan run3646

Other Status Updates

• Accumulated charge =
• bcm_dg_ds pedestal map has been updated HAPLOG
• started burpcut since slug13
