    Shift crew ***Marat Rvachev, Zhengwei Chai, Bitao Hu***

    0:00 Contunue taking data on kinematics 32
    1:19 OTR reads 0.28mm "x width"
    1:22- 1:33 No beam
    2:50 - 3:05 No BPM signals read out (no signals from both BPMs in datastream too;
    run #2986); after recovery saw that beam position drifted by ~0.3mm.

    He3 production runs this shift:
