RC Summary

Thursday, 18 Mar. swing through Friday, 19 Mar. day

Several hours used for investigation the Hall B "shoulder", which seems to have been a cabling problem!
BCM/BPM/LUMI calibration
IHWP is OUT.
LH2 target parity quality
- 8.5 hours of good data for this 24 hr period (runs 20688-20715) out of 16 hours on tape.
- Overall efficiency: 35.4% (8.5/24) (Not as bad as it might be what with the Hall B work and the calibration)
- Beam (no trip) efficiency: 65.2% (9.2/14.1) [Probably reflects the BCM calibration---low current.]
- Parity efficiency: 92.4% (8.5/9.2)
- Total parity hours: 22.0 (runs 20584-20715)
- Overall IN/OUT charge ratio: 0.0
N.B. Jeff Martin has resumed as run coordinator. Damon Spayde takes up the sacred cell phone on the 22nd.

Production running at 40 渙 and running with 6 mm halo target.

Primarily LH2 production running.
We will stop at roughly 9:00 AM every day for 1/2 hour to perform Chow's fOps test plan until further notice.
The next polarization sequence (Moller measurement, followed by IHWP reversal (to IN), followed by another Moller measurement, and then a RIP scan) will take place, on Friday, March 19th.

Det 13, 14, octant 4 and 8 show width = 1.2 * statistical. Jacques Arvieux and Christophe Furget are investigating. Possible resolutions: cable wiggling, cable fixing, DMCH replacement (they
Spikes in the French timing spectra appear from time to time. Under investigation by Jacques Arvieux
Preparations for transverse running are not yet finished.
