    Day Shift Summary

    SL: Melissa Cummings
    TO: Pengjia Zhu
    3rd: Eric Fuchey

    08:00 Start of shift, taking production data for p=0.75270
    10:15 Start target anneal. Pengjia is also doing his BPM scan.
    10:45 BPM scan is done. Called for escorted access so that target RF generator can be power cycled. Parasitic experiments will also do some work during access.
    12:00 Back to power permit.
    12:10 Starting beam recovery procedure - seems the beam is still centered
    12:20 Change LRHS momentum to 1.1511 (elastic setting) for packing fraction run
    12:45 After cycling the quads the nmr on the LHRS won't lock. Changing the probe doesn't have any affect. The nmr field reading would oscillate between 0.6T and 1.6T, where the field should read ~0.4T for this setting. Finally, by tuning off the "search", we were able to get the nmr to lock. In the meantime, top target cell was polarized to +39%.
    13:30 Finshed with packing fraction run, moved LHRS back to p=0.7527 and resumed production
    16:00 End of Shift, still taking production data for p=0.7527



    Runs Taken:

    Production:
    5208/24034/41840 HWP OUT
    5209/24035/41841 HWP changed to IN at end of run (see halog post 380048)
    5210/24036/41842
    5211/24037/41843
    5212/24038/41844
    5220/24043/41848 HWP OUT (LHRS dipole changing)
    5221/24044/41849
    5222/25045/41850
    5223/24046/41851
    5224/24048/41852 RHRS CODA crashed during 24047
    5225/24049/41853
    5226/24050/41854
