    Calibration runs for kinemtics #28

    16:00 2489 10 cm Al dummy target with raster ON, I = 30 micro Amperes.
    2490 10 cm Al dummy target with raster OFF, I = 5 micro Amperes.
    2491 4 cm Al dummy target with raster OFF, I = 5 micro Amperes.
    2492 12C target raster OFF, I = 50 micro Amperes.


    17:05 We asked for acces in order to change HRSH angle above 82 deg.
    and we started the momentum change. The new kinematics is #29:
    theta_HRSH = 89.95 deg (requested angle)
    p_0_HRSH = 1171 MeV/c. (requested value)
    18:00 End of access.
    18:15 Beam back
    18:17 Harp scans + CODA run with new PS:
    with raster OFF: gain 8 on both scanners I = 5.15 micro Amperes.
    scan_556.dat and scan_557.dat + run number 2493.
    with raster ON: gains 64 (#5) and 32 (#6), I = 5.3 micro Amperes.
    scan_558.dat and scan_559.dat + run number 2494.
