    Entry number 357257

    keyword=Swing shift summary

    Hall in controlled access (Left Q1 being fixed) at start of shift.

    Beam back by 17:00, Began running ~17:15 with left arm only: Right dipole still ramping up.


    19:35 Right arm is settled, start taking production with 2 arms.
    Dipole still drifting a little, so have to check data to be sure it's stable enough.

    19:30 ~30 min. of useless beam (constant trips). Come back ~20:00 with stable beam at 110 uA.

    Continue data taking: 6400 events so far. (~1750/hr with both arms)
