Thursday, February 16
- Accelerator Status
- Stable accelerator running over the last 24 hours
- Harp scans:
- MCC scans before and after Todd's script
"Good enough -- horizontal convergence is nearly spot on, and vertical convergence is a little shallow but ok." - Our scan: before and after Todd's script
- 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."
- Beam sigma at the radiator: 0.6cm (Feb 15) vs 0.5cm (Feb 9)
- Work on RF separation will start at 7:30 AM today and last for 2-3 hours
- Hall-D/GlueX items
- In the last 24 hours:
- ABU 17.66 hrs (4.97 + 6.37 + 6.32), BANU 2.21 hrs (1.27 + 0.40 + 0.54)
- Total triggers collected: 1856 M
- A usual assortment of DAQ crashes
- RootSpy tips:
- Restarting cMsg server
- Multiple instances of RootSpy on gluon47
"... no more than 1 or 2 instances running in the counting house at any point in time."
- New BCAL gain constants in ccdb [5]
- In the last 24 hours:
- Monitoring
- A new instance of 32ns ADC-TDC offset: [6]
- Run Plan
- 7:00 AM - 7:30 AM ==> Hall safety walk-through (After RADCON does it job)
- 7:30 AM - about 10 AM ==> MCC works on RF separation
- A new harp scan after RF separation work is done
- Production data
- Offline Analysis?
- Any Other Business?
