    keyword=current ramp-up continued

    After about 1.25 hours of access to raise trip level, we
    can continue the ramp up of current on lead target.
    run....time......current.......temp........rate
    .........min.........muA.........K(/10)......kHz
    2253....0..........5.1............132..........11.9
    2254....5..........20.4...........196.........51.8
    EPICS/medm reading of BPMs 4A,4B stop
    working. But the CODA data looks ok.
    2256....10.........25.............252...........62.7
    2257.....15........30.............281...........73.7
    2258.....17........35.............313...........87
    2259.....19.........40............327...........91
    2260......24.........45............356..........104
    2262......30.........50............................110
    Will leave it at 50 microamps for about an hour.
    .............45..........50..........403...........108
    2263.....53..........50..........417...........105
    Noticed beam drifted to (-0.2, 0). Asked MCC
    to fix this to (0,0). After this
    2265.....63.........50...........417...........95
    The beam position is very unstable. It dances
    around by 200 microns on the EPICS screen.
    Fast feedback is not working.
    ...........80...........50...........413.........95
    ...........82....notice Q1E tripped off.
    We cannot reset it. Test is finished.
    Mark Stevens is coming in anyway. He can fix it.







    Note that T2 ~ 0.9 T1. Lots of junk.
