    Entry number 199662

    keyword=Shift summary

    16:00 Starting the run waiting for the right dipole to set at
    0.6443 GeV/c.

    16:12 Start 1st run at this kinematic. run# 2664

    19:51 Right arm VDC HV raised to 3.6kV.

    20:28 LQ3 fluctuating. Then LDipole current dropped.

    20:46 Left magnets are fine now. Resume production

    21:44 MCC needs to decrease the beam current to 85uA.

    22:13 Moving target to dummy

    22:23 Target is in position. Ask for 40uA (=limit on Al dummy).

    23:06 Start kinematic change: going to Q2=50 fm-2
    23:43 Magnets ready.
