    keyword=Shift summary

    16:05 - changing the field on the RHRS:
    * Q2/Q3 are recycled (1600 A)
    * Momentum is set to 0.79362 GeV/C

    LHRS is not responding yet (at work)

    LHRS was moved to the correct position: 112.46 degrees. Floor: 112.5, Vernier: +25.
    RHRS was moved to the correct position: 21.25 degrees. Floor: 21, Vernier: +9.

    LHRS momentum:
    * Q2/Q3 are recycled (1400 A)
    * Momentum is set to 2.02372 GeV/C

    Untill 18:00 - There was a problem with the doors of the Hall. It wasnn't possible to close them. Now it is fixed. We are ready for data taking.

    Untill 18:30 - The optic target wouldn't move. The problem was fixed (see Halog).

    Untill 20:45 - Beam was not delivered due to electric shortage in one of the buildings.

    21:20 - Beam is transferred to HallA. BPMs were adjusted.

    * CODA fell. Had to reboot the ROCs and "startcoda" on adaql2

    21:40 - starting optics run: 1566 - optic target, raster off, radiator out.

    21:53 - Change target to He3.

    22:00 - Take He3 data
    run 1568:
    The run used to define prescalers and check the raster. Raster size was too big, but while trying to fix it the beam was stopped due to beam adjustments in HallB (last 10 min. of run time).

    run 1569: He3 target, 45uA, raster on, Radiator in. prescalers are not fixed yet. Rate is high.

    run 1571: Good production data

    run 1572: He3 target, 45uA, raster on, Radiator in. PS11 died, had to kill CODA and reboot it.

    23:40 - start to take data again.
    run 1573: He3 target, 45uA, raster on, Radiator in.

    00:00 - radiator out runs 1574, 1575
