    keyword=Shift summary

    08h00 Beam is off since 15 min.Problems with an RF cavity and MCC is waiting
    for injector people to come in.
    08h30 Beam is back (not for a long time because of incoming tuning)
    08h34 Beam is off, injector people are now in.
    09h03 We started a PEDESTAL run.
    10h24 Beam is back.
    10h30 We requested the beam current be reduced to 120 microA , since the beam was not steady, was tripping all the time.
    10h45 there was a gas low pressure alarm, paged Jack.
    11h40 MCC called and said they are doing some beam tuning for 15 minuites.
    13h00 For the third tim ewe had to reboot CODA since coda rate fell down and the ROC's were not responding.
    13h19 MCC is trying to adjust our denergy curve with Hall C one. It went worse:
    about 200keV OFF!!!!
    14h49 Previous problem still not fixed and in addition there are problems in the injector....
    15h00 Mcc is going to test the OTR. Target needed to be rebooted.
    at 15 uA: x_width_OTR = 0.193 mm and y_width_OTR = 0.121 mm.
    at 50 uA: ............................0.172 mm ....................................0.122.......
    15h27 Acceptable beam is back.
