    keyword=Owl Shift Summary

    A. Tobias, Khem Chirapotpimol and lots of help from Jin Huang.

    00:00 Earlier in the Swing Shift, we requested MCC to tune beam into Hall A thru Compton Chicane onto our BeO screem with BPMA X=0 Y=1.7mm and BPMB X=-1.5 Y=1.2mm.
    00:44 MCC calls us and asks what beam size we want. I tell them 100-200um sigma both X & Y.
    01:15 We Request MCC to continue trying to get requested BPM positions.
    02:10 Finished w/ multiple adjustments to BPM positions to "center" beam just -1mm to the left on the BeO screen.
    the following are in MCC raster units ...
    02:12 Do a couple of Hall A Target OTR tries (snapshot OK) and HARP scan to check X & Y sigma (less than 200um).
    02:40 Put BeO screen back in with 3x4 raster and check spot++.
    02:55 Request 3x4 raster on 20psig N2 in REFERENCE CELL w/ 2uA beam.
    03:02 Request 4x5 raster. Check scalars & spot++.
    03:13 Request 6x6.6 raster. Check scalars & spot++.
    03:30 Go back to 3x4 raster and start Xin's BCM Calibration w/ 1ATM N2 in REFERENCE CELL w/ beam current from 2uA to 15uA in steps of 2uA.
    06:00 Let MCC do some optics measurements in A-line (go to empty).
    06:23 Start 1hr production run on 20psig N2 REFERENCE at 12uA. This run does not have RICH since deadtime is too high 41%.
    07:40 Take some Carbon Optics Target data to check collimator issue.
    07:50 Alexandre takes look at RICH detector issues.
