Production Run List
- Since we are using bcm_dg_ds, the width in the bcm asymmetry is 2X of what we had with bcm_an_ds
- 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
- Lower SAM3 HV?
Start Slug 15, IHWP OUT, FFB on always

- Good - run3682ADDED from suspicious list
- MCC was trying to fix the problem in hall B
