Friday, February 17
- Accelerator Status
- Hall was in controlled access from 7:00 till 16:30 for RF separator studies

- Production restarted at 17:30
- Stable beam since then (max 10 minutes off on 2 occasions) [41]
- Radiation levels are about the same as earlier [42]
- Harp scans: MCC and ours.
- In terms of (Sigma_X, Sigma_Y) at 5C11, 5C11B and radiator:
- (0.83, 0.32), (0.63, 0.24), (0.68, ??? - the fit has failed)
- Beam is ~20% tighter in X and twice narrower in Y comparing with a day ago
- Photon transmission is about the same as a day ago
- In terms of (Sigma_X, Sigma_Y) at 5C11, 5C11B and radiator:
- BPM calibration?
- AD00 BPM is no longer the same as AD00C BCM but only 40% of it [43]

- In terms of (Sigma_X, Sigma_Y) at 5C11, 5C11B and radiator:
- Before: (1.31, 0.63), (1.08, 0.73), (1.03, 0.41)
- After : (1.07, 0.51), (0.79, 0.50), (0.78, 0.32)
- MCC scans before and after Todd's script
- Convergence studies from Hovanes: Feb 15 vs Feb 9
- Beam sigma at the radiator: 0.6cm (Feb 15) vs 0.5cm (Feb 9)
"... uncertainties ... a lot larger compared to Feb 9. It is hard to make any conclusions about the improvement of the spot."
