    keyword=Shift summary

    16h00 : Shift begins, while running run 2807
    17h30 : MCC calls to say they have a problem with the beam and it will be off during a few minutes. We end the run 2807, and set the new number of events to 1.5 M.
    18h05 : MCC calls to say they will restore the beam with very low current.
    (Hall C is in set in controlled access).
    18h13 : MCC calls to say they will restore the beam. We will start a new run when beam will be OK
    18h21 : They have still problems with the beam , so it will take more times. Beam off.
    18h36 : They will restore the beam.
    19h04 : The beam was oscillating at ~40microA, when they call to say they will make a few tests, and turn off the beam. No shift started because we were waiting for a 'stable' beam.
    19h17 : MCC call to say they will restore the beam again.
    19h25 : Beam seems to be stable, but the current is ~48microA. Start run 2809.
    19h56 : MCC calls : they will try to reach 75microA.
    20h34 : MCC calls to say they will try to increase current to 100 microA
    20h44 : MCC calls to say they have problem with high currents so the intensity will be set back at 75 microA
    22.22 : MCC calls again : Beam will be down for some time.
    22:50 : MCC calls to let us know that they have had a lot of BCM trips due to vertical beam motion. This is from a magnet malfunction. They will deal with it in the morning.
    00.00 : Shift ended while running 2811.
