    When we arrive, the magnets are settling. We perform a check of
    raster size (runs 4067, 4068), adjust it to approx 3.5 mm square.
    The intrinsic spot size was already checked, see:
    HARP and OTR.
    Some Compton tuning subsequently done, but OTR width did not change.

    Run ............. Comment
    24069 / 4069 .... C12 multifoil, kine 11.1 (P = 3.137, sept. 413.5)

    02:09 Set kine 11.2 : P = 3.046, I_sept = 400.66
    24070 / 4070 .... C12 multifoil, raster remains off
    24071 / 4071 .... C12 multifoil, raster on
    24072 / 4072 .... junk, tried empty target but beam unstable at
    ................. 10 uA. But eP ion chamber trips -> go back to 5 uA.
    24073 / 4073 .... again tried empty tgt, raster on, but junk due
    ................. to RF trips. MCC stops for Q.E. measurement.
    24074 / 4074 .... Empty target, raster on
    24075 / 4075 .... Empty target, raster off
    24076 / 4076 .... Empty ref. cell. Raster on.
    24077 / 4077 .... Ref. cell N2. Raster remains on.

    04:36 Set kine 11.3 : P = 2.955, I_sept = 387.7
    24078 / 4078 .... Carbon multifoil. raster off.

    05:37 Access to remove sieve slits & install target collimator.
    Set kine 11.10 : P = 3.137, I_sept 413.68.
    Septum got stuck at 409 amps. So we put P = 3.104 GeV/c.
    24079 / 4079 .... Carbon multifoil. raster off. Junk, wrong PS.
    24080 / 4080 .... same, but correct prescale factors
    24081 / 4081 .... Carbon multifoil. raster on.
    Switching to empty ref cell as shift ends...
