    Swing shift summary

    16:00 Swing shift starts. Production
    16:39 - 16:45 Changing L-HRS to P0L=1054.81 MeV
    17:45 - 17:52 Changing L-HRS to P0L= 950.22 MeV
    17:45 - 18:23 Changing R-HRS to P0R= 983.47 MeV
    18:46 - 18:49 Changing L-HRS to P0L= 916.96 MeV
    19:55 - 20:19 Changing R-HRS to P0R=950.22 MeV
    19:55 - 19:59 Changing L-HRS to P0L=854.94 MeV
    20:59 - 21:07 Changing L-HRS to P0L=1254.19 MeV
    21:22 - 21:56 Changing R-HRS to P0R=916.96

    21:27 Boiling tests. Rates too high, runs are less than one minute and dead time is about 50%. Calling Nikos

    Answer: Quasielastic contribution too high. The momentum change in the right arm has finished, so we change to production in the right arm.

    Change left momentum spectrometer to 1285.55 MeV

    22:14 - 22:17 Changing L-HRS to P0L=1285.55 MeV

    Nikos called: Change left momentum spectrometer to 1298.09 MeV

    22:25 - 22:30 Changing L-HRS to P0L=1298.09 MeV
    23:02 - 23:40 Changing R-HRS to P0R= 854.94 MeV

    23:10 Start boiling tests on Carbon
