    keyword=Swing Shift Summary

    16:00 we continue production on C target, p0L = 138.5 MeV, p0R = 153.07 MeV

    16:10 We lost IOC on Right Spectrometer. We rebooted IOC.
    Moved to H2 target

    16:45 Moved to Pb target

    17:35 target IOC crashed, at the same time readouts of the target temperature are gone, very probably out of power. We rebooted target IOC but we need an access

    18:15 Controlled access

    20:35 JP, Zein-Eddine and Dave fixed problem with power supply at target, we come back to beam permit

    20:45 we restore production after checks of beam and target.

    21:10 new momentum settings: p0L = 125.493 MeV, p0R = 138.493 MeV
    I see the Right Arm not responds to the momentum settings. I look and I found that the p0 regulators were OFF and the Dipole setting was wrong even if the value was green and no alarm was sounding. Therefore I worry that Right Arm data after rebooting IOC of Right Arm are junk

    22:05 H2 target in

    22:35 Carbon target in

    22:38 Pressure on loop 3 went down, alarm, we called JP who told us how to operate on solenoid valve to increase pressure

    23:10 Iron target IN

    23:24 Lead Target IN, new p0L = 113.37 MeV
