    Owl Shift for Tuesday May 2nd, 2007


    Leader:   Bryan Moffit
    Target:   Nikos Sparveris
    Beam Energy = 4.501 GeV
    Starting Spectrometer settings:
    Left arm: Angle = 21.546° p0 = 3.728 GeV/c
    Right arm: Angle = 68.328° p0 = 0.727 GeV/c
    Change at 00:35 to:
    Left arm: Angle = 20.40° p0 = 3.755 GeV/c
    Right arm: Angle = 69.41° p0 = 0.686 GeV/c

    Summary

    Smooth production data taking. Began warming up target, at the end of the shift.

    Significant Events

    • 00:00 Began shift in the middle of Run 3078 on the Al dummy target 40µA.
    • 00:35 Move to 4He target... begin changing kinematics to Q2 = 50 fm-2
      Left arm: Angle = 20.40° p0 = 3.755 GeV/c
      Right arm: Angle = 69.41° p0 = 0.686 GeV/c
    • 01:13 Start taking data again.
    • 05:40 Target yellow alarm. Target Software calculated zero heatload from beam (for 1 second), when the beam was still on.
    • 06:20 Incoming Call: RC (Status Check)
    • 07:23 Move to Al dummy target.
    • 07:37 Start target warm up.
    • 08:00 Passed Run 3097 to Day Shift.
