    -----------------
    BeO target
    -----------------

    Run
    1061 BeO target, harp scan 1961
    1062 BeO target, dominated by singles
    1063 BeO target, dominated by singles
    1064 BeO target, dominated by singles
    1065 BeO target, dominated by singles
    1066 BeO target, dominated by singles
    1067 BeO target, harp scan 1962
    1068 BeO target, raster on 1.8mmx1.5mm, dominated by singles
    1069 BeO target, raster on 2mm x 2mm, dominated by singles
    1070 BeO target, DAQ error

    17:10 turned on raster, started checking spot size, All BeO target
    Run 1068 got 1.8mm x 1.5mm. (Mag currents 10.5 A x 10.6 A)
    Run 1069. Requested 2.2x2.5, got 2mm x 2mm (Mag currents 11.6 A x 13.2A)
    Run 1070, Changed prescales to emphasize coincidence data. DAQ hang.
    Run 1071, new prescales
    Run 1072, Final raster setting. about 1.9mm x 2 mm


    -----------------
    LH2 15 cm target
    -----------------
    1073 First Data on LH2! 5uA. No visible change in target parameters,
    small change in septum temperature.
    Changed prescale to match suggested trigger rates at 25 uA.

    1074 new prescale settings on LH2. At 13 uA, we see 900 Hz in DAQ, so
    I mis-calculated. RICH tripped at the this current, but recovered
    when reset without lowering beam current.
    One coil on Right Septum reached 7.2 K.

    1075 Reduced current to 9 uA. (LH2) RICH HV = 2050V

    1076 RICH HV = 2000 V.
    1077 RICH HV = 2000 V.

    -----------------
    LH2 4 cm target
    -----------------

    1078 RICH HV=2000 V. Ramping to 30 uA.
    1079 RICH HV=2000 V. 30 uA.
    1080 RICH HV=2000 V. 35 uA.

    -----------------
    Optics check
    -----------------

    1081 "10 cm" Optics target 10 uA, raster on. Prescales are wrong, try again.
    1082 "10 cm" Optics target 10 uA, raster on.
    1083 "10 cm" Optics target 10 uA, raster off.

    1084 "24 cm" Optics target 10 uA, raster off.
    1085 "24 cm" Optics target 10 uA, raster on.
    "10 cm" reconstructs to two foils, 24 cm apart,
    "24 cm" reconstructs to two foils, 10 cm apart,


    1086 4cm LH2, 40 uA.
