    Entry number 236812

    keyword=Swing Shift Summary

    16:00 continuing data taking on H2 at Kinematics B, run 4669

    16:15 Move to dummy target, run 4670

    16:35 Asked for Controlled Access as scheduled
    Richard Lindgren went downstair.
    Moved HRS Left Momentum to 1.194 GeV
    Moved HRS Left to 14.5 deg
    Moved BB to 31.1 deg

    New Kinematics setting is Kinematics F

    17:30 JP is downstair to fix target fan problem
    17:45 JP fixed the target fan, we ask for beam back

    17:55 Ta target in
    18:10 set prescales to match designed rates

    18:15 start run 4671

    18:20 apparently Dead Time is 31% even if we set prescales to have Dead Time < 15%, we do not know if it is a real problem or monitor failure

    18:25 FSD Tripped on the beam line.
    18:30 Beam is back, we start run 4672

    18:45 Moved to Carbon Target, run 4673

    19:10 Moved to Hydrogen Target, Moved to 1147 MeV on HRS-Left

    Start production on kinematics F (III).

    19:15 Start run 4674. Now Dead Time is OK

    20:15 Big Bite MWPC tripped two times in 30 minutes, during run 4675 and 4676.

    20:45 we start run 4677
    21:00 started run 4678
    21:05 Big Bite MWPC tripped again
    21:10 run 4678 ended
    21:20 started run 4679
    21:45 started run 4680
    21:53 started run 4681
    22:07 started run 4682
    22:23 started run 4683
    22:41 started run 4684
    22:52 started run 4685
    23:06 started run 4686
    23:22 started run 4687
    23:36 started run 4688
    23:51 started run 4689

    Shift ended with run 4689 runninng, then Dummy Al target should go in
