- Detector mounted to motorized stage, powered up nominally at 0845. Allow 15 min to stabilize.
- Failed 'epix10k_pedestals' script. Detector looks good in AMI (considering no peds).
- ~0930 Q1 tripped....reset with wider env limits.
- Silke thinks pedestal script is fixed...'epix10_pedestals', then 'makepeds' to load. Seems good. Check timing first.
- Move integration window via acqToasicRDDelay (1 unit = 10ns). Started ~78032, verified off at 68032, so good @78k.
- Ag behenate, all five gain settings. No attenuation. Hi/Lo gain autorange is no good. Quad 1 is way off.
- Set fixed high, make new pedestal, record ring shape for geometry.
- While checking motion limits to adjust ring coverage, we handed off the beam to AD and they were unable to return it for a couple of hours....

Somewhat mitigated by the fact that this detector has already been extensively run by TVD, and we have other data giving ring/geometry info as well as gain info under flux. We do have some full-beam rings to study that should include some gain-switching for comparison with previous data.
