    keyword=BB check-out with D2 target now

    After production on multi-12C, we started checkout of BB on reference D2 target. Miha and Jin Ge are doing the checkout. Right arm+ND are taking production data during this time period.
    Left+BB deadtime: with only ~500 Hz DAQ rate (5uA on 100 psig D2 target, with PS5=1, PS6=2, PS3=20,PS4=8), deadtime is ~20%, similar to the previous situation with over 1KHz DAQ rate, 5 uA on multi-12C.
