Daily Meeting BlueJeans
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
Issues
Other Status Updates
- Accumulated charge =
- bcm_dg_ds pedestal map has been updated HAPLOG
- started burpcut since slug13
