Run Coordinator's Report for Thursday December 9 Day through Friday 10 Owl

Summary

There is an open day shift on Monday, December 14, 2009, and a few open shifts 18-22 December. Please sign up!
Beam is scheduled to turn off at 07:00 on 22 December.

During day shift, we took a set of Moller measurements, including the beam current scan and the laser phase study. See HALog 305990 for a summary.

During swing shift, we took a set of multifoil and single foil carbon runs, and a set of aluminum dummy target runs. We collected about 2 hours of 50 uA data on the dummy target for PV background measurements from the aluminum. See these HALog entries for the Q2 and W plots for the multifoil 12C target, single 12C target , and aluminum dummy target.

At the end of swing shift through the first quarter of owl shift, there was an extended down due to RF problems. Some additional work related to the recovery from this will need ot be done today (to try to keep it from failing over the weekend).

We achieved 14 hours of ABU in the last 24 hrs. Slug 21 was begun at 9am on 9 December; as of the end of owl shift, it had 546.5k good pairs.

After recovery, the plan for today and the weekend is to take production data on the LD2 target.

The IHWP will need to be flipped (and the flipper script run) when we get 10^6 good pairs. Shift crew should speak with Hall B and determine a specific time about 4 hours before it needs to happen. Be sure you have an expert available to do the flip at that time. Call the RC if there are problems.

We may do the boiling study and a BCM calibration run over the weekend, but they may be delayed until early next week.

There is an open day shift on Monday, December 14, 2009, and several open shifts 18-22 December. Please sign up!
Shift Leaders: please write a detailed shift summary ( here is a great example) and submit the BTA for each shift. Please log CODA reboots in the halog and shift summary.
3rd person: Please make sure to start and stop the HRS DAQ at the same time as the parity DAQ and to do the prompt analysis and the HRS analyzer for every run.
3rd person: please keep a careful eye on the online data display. Most problems can be caught quickly this way.
Please make sure that the shift checklist is done once each shift.
