    keyword=Swing shift summary

    16:00---Shift starts. Kin (155,0). Continue taking prodution data at this kinematic setting.

    E_beam = 4537.98 Mev, LH2 15cm Target, 1.5+3 in. Carbon, 6msr coll. in both arms.
    P_e = 3.6600 Gev/c, Angle_e = 14.704
    P_h = 0.7418 Gev/c, Angle_h = 34.731

    From the replay results of run 1723, with the proton ,vertex difference and
    missing mass cut, the signal to noise ratio is 7:1 (25uA beam current).

    19:04---Ask MCC to send 50 uA current to Hall A.
    22:32---Beam tripped. MCC is having some problem with the RF module.
    It will take 15min or more time to fix it.
    23:01---Beam back to hall A.
    00:00---Start to change kinematics. At the same time take e-arm sieve slit data.
