    keyword=shift summary day shift

    8:20 beam comes back
    9:00 right septum trip
    9:30 septum is back
    10:30 bulls eye and raster studies
    13:10 back to production
    13:30 run 4960 beam postion was unstable at the beginning
    (fast feedback not working ???)
    15:01 nearly all epics fields went white, iocha14 did not come
    back, lost left magnets during reboot
    15:30 right septum tripped

    4958/4959 junk to test prescaler factors and raster

    standard prescalers
    -> beam postition unstable, probably junk
    4961 production run at 55uA, waterfall at 615
    4962 production run at 55uA, waterfall at 615, lost slow control, but
    should be fine
    4963 production run at 55uA, waterfall at 615, lost right septum
