    Shift summary for Owl shift, 8/26:

    12AM - No beam, currently tuning.
    12:35 - Change to thin tantalum
    12:40 - Changed magnets to the PREX tune.
    12:50 - 5 uA beam on the flat, 1cm PREX detector (runs 4331-4).
    2:00 - Changed to thick tantalum target.
    2:05 - Request MCC ramp up the beam on the thick tantalum target to 100uA. Begin the MCCs program for current ramping
    2:57 - Switch to empty target, per MCC request
    3:26 - Switch to thick tantalum target, per MCC request
    3:28 - Switch to empty target, per MCC request
    3:30 - MCC ramps current up to 100 uA
    4:20 - Reach 100 uA, switch in thick tantalum.
    5:30 - MCC informs us that achieving 100uA on the thick target will require changing ion chamber trip levels. We agree to recieve 30 uA.
    5:35 - Recieve 30uA for oversampling tests on the lumis (4335-8)
    6:13 - Stop lumi tests, call for access to change detector configurations
    6:55 - Switch to 45 deg. angled PREX detector configuration. MCC says beam is currently down.
    7:30 - Recieve beam from the MCC, test the 45 deg. config. (4339-4341).
