    keyword=Shift Summary

    We finished to take data at 270 deg :

    RUN 3136/31136----372K/329K----4.983/4.443----9.426
    RUN 3137/31137----401K/355K----5.384/4.798----10.182

    12:30 We finished to took data at 270 deg Beam HWP OUT.
    12:40 NMR/EPR 40.2/39.4%

    We moved the holding field to 90 deg, put the target HWP to IN position.
    1:10 We asked for beam

    RUN 3138/31138----376K/343K----0.376/0.343----0.719
    RUN 3139/31139----372K/348K----0.748/0.691----1.439
    RUN 3140/31140----367K/331K----1.115/1.022----2.137
    RUN 3141/31141----382K/336K----1.497/1.358----2.855

    4:20 we stop taking data at 90 deg.
    Moved to BeO target and steer (5 uA) beam to (0,0) BPMA and B.
    4:35 moved to reference cell, asked for 10 uA beam.
    taking 20 mn of data, everything is fine with the steering.
    5:05 We filled the reference cell with nitrogen.
    5:10 Beam is back, taking 20 mn data.
    5:30 We stopped taking data and ramping down the left spectrometer.
    5:45 Ed Folts came.
    6:00 We Made a Controlled access to change the polarity of the left spectrometer.
    6:40 We ramped the magnets.
    6:40 NMR/EPR
    6:45 MCC told us that the slit at the injector is broken. estimation time to recovery is 2 hours or more....
    7:35 The dipole of the left spectrometer is quite "lazy" to reach the value of 2.29 GeV/c.
    Let the next shift taking care of the situation.
