    Entry number 217254

    keyword=owl shift summary

    Started the shift with polarity change completed on the magnets
    and waiting for beam. The beam arrived at 01:40.

    R-HRS runs with electrons.
    L-HRS runs with positrons.

    ---------------------------------------------------------------

    Here are R-HRS runs
    Run / start time / target / events

    -- P0 = 143.84 MeV --
    21285 / 01:42 / dummy / 275K
    21286 / 01:55 / carbon / 186K
    21287 / 02:14 / iron / 207K
    21288 / 02:34 / lead / 529K
    21289 / 02:50 / hydrogen / 333K
    21290 / 03:04 / helium / 294K

    03:22 Change P0 to 124.18 MeV.

    21291 / 04:35 / carbon / 153K / dipole at 123.97 MeV
    21292 / 04:52 / iron / 188K / dipole at 124.00 MeV
    During run 21292 the dipole oscillated between 124.00 an 124.06
    (But the P0 regulation is on)
    After this run (21292) we change L-arm momentum and let
    R-arm settle more. Dipole is mostly "in the green" now.
    21293 / 05:07 / iron (repeat) / 190K / dipole at 124.08
    21294 / 05:24 / hydrogen / 400K
    21295 / 05:36 / lead / 1078K

    05:54 Change P0 to 112.349 MeV

    R-arm dipole was "in the green" at the start of the following run.
    21296 / 06:20 /carbon / 260K / dipole is drifting 0.1113 to 0.1117
    21297 / 06:45 / iron / 352K / dipole 0.1117 to 0.1120
    21298 / 07:12 / hydrogen / 308K / dipole was ~0.1121
    21299 / 07:23 / lead / 1M
    21300 / 07:51 / carbon (repeat) / This will go until 8:15
    We repeated carbon because we're going to open the hall at 08:15
    letting next MCC shift to do survey.

    Here are L-HRS runs
    Run / start time / target / events

    -- P0 = 147.89 MeV --
    3049 / 01:42 / dummy / 256K
    3050 / 01:55 / carbon / 162K
    3051 / 02:14 / iron / 220K
    3052 / 02:34 / lead / 592K
    3053 / 02:50 / hydrogen / 326K
    3054 / 03:04 / helium / 320K

    -- P0 = 133.10 MeV --
    3055 / 03:28 / helium / 330K
    3056 / 03:42 / lead / 680K
    3057 / 03:58 / hydrogen / 380K
    3058 / 04:12 / dummy / 290K
    3059 / 04:23 / carbon / 143K
    3060 / 04:35 / carbon (repeat) / 139K
    3061 / 04:52 / iron / 205K

    -- P0 = 124.18 MeV --
    3062 / 05:07 / iron / 182K
    3063 / 05:24 / hydrogen / 312K
    3064 / 05:36 / lead / 933K
    3065 / 06:03 / carbon / 124K

    -- P0 = 112.349 MeV --
    3066 / 06:20 / carbon / 220K
    3067 / 06:45 / iron / 371K
    3068 / 07:12 / hydrogen / 338K
    3069 / 07:23 / lead / 1.3M
    3070 / 07:51 / carbon (repeat) / This will go until 8:15.
    Then we have controlled access planned and a sweep required.
