    keyword=Owl Shift Summary


    SL: Ryan Zielinski

    3rd: Tobias "Nevernude" Badman



    00:00 Shift begins and finishing up optics. Starting with Acceptance Study Part I.
    00:25 Finished Acceptance Study Part I and called for Escorted Access to Remove Sieve Slits
    00:40 Sieve is out. Reading to resume optics.
    00:45 IHWP is now OUT
    00:50 LH3 filled back into nose. Draining it again so we can resume optics
    01:10 Finished Acceptance Study Part II, turning rasters off
    01:10 Slow Raster is 1.4 V should correspond to 2cm
    01:30 Optics is finished. Refilling nose with LH3
    01:40 Moved LHRS to NH3 Elastic
    01:45 Rasters back on, starting Dilution
    02:15 Dilution runs done. Moving to NH3 to start Packing Fraction
    02:35 Noticed LHRS set to 2.279 instead of 2.2279 so all of previous dilution runs for LHRS not valid. And TOP NH3 PF not valid.
    02:40 Redid LHRS PF runs
    02:55 Noticed Target magnet power supply dropped half an amp. Fixing this so we can polarize
    03:15 Can't ramp up magnet to correct field. Calling in target expert. James is on his way
    03:45 Magnet software wasn't reading persistent current correctly because of software bug. See Jame's HALOG for a better description
    04:00 Beginning polarization of bottom NH3
    04:10 STARTING PRODUCTION with polarization of -80%
