    keyword=beam hit something?

    @ 0738 when we got tune beam back, the beam was too low by 6 mm. this was seen both on the BPM stipchart (left) and the Target Ion Chamber (right).

    BPM strip chart:
    maroon = BPMA is Y position
    turquoise = BPMB is Y position

    ION Chamber strip chart:
    maroon = target ion chamber
    red = RDipole settting
    purple = Q1 current
    orange = septum current
