    Summary of shift 8-16h

    ! New crew at 8:00 ;-)
    Serge Kox (SL), Eric Voutier /Raphael Tieulent (TO),
    Akila Frahi-Amroun + Eric Liatard (SW)

    Change beam Intensity from 80 to 100 microA at 8:30
    Stop run 2016 at 8:30 1M events
    Start run 2017 at 8:30, same settings
    Stop run 2017 at 9:45

    ! Harp scan started at 9:55 (5 microA, OTR on, 12C, raster off)
    --> Results recorded, OTR OK for beam energy (<200 microns in X and Y), runs 411 and 412
    Start run 2018 (check raster, 5microA, 12C, raster ON)
    Start run 2019 (check raster, PS: 1 for singles)
    10:20 Accelerator off

    ! 10h20 Back to normal conditions (OTR off, 3He target, 100 microA, raster on, fast feedback on, PS: 60,12,50,1, 65000)
    Waiting for beam ... back at 10:50
    Start run 2020 at 10:50 (beam around 90 microA, some trips)
    Stop run 2020 at 12H:10.
    Start run 2021 at 12H10 (many short trips, fast feedback went to Standby sometimes during the run)
    Stop run 2021

    ! 12:50 12C run (OTR in, raster off, 50 microA, PS:1,1,1,1,2,1,65000)
    Start run 2022 (stop 10 mn later, 200K events)

    ! 13:10 Changes in the plans ... >:-((
    Controlled access:
    Angle change for electron and spectrometers (13.09/34.69)
    Momentum changes for electron/hadron spectrometers (1.944/-1.5)
    Problem with electron dipole power supply
    Back to runing condition at 14:55

    ! 3He elastic (10microA, fastfeedback on, raster on, 3He target, OTR off, PS100,2800,7,2,1,65000)
    Start run 2025 at 15h ... ooops, bad angle set for the hadron arm !
    Stop the run and go from 36.4 to 34.7 for the angle of the hadron arm
    15H15 Start run 2026 with good settings
    Checklist done
    15h30 Start run 2027
    15h40 Start run 2028
    15h50 Start run 2029
    end of the shift




    >:-| Level of He for the Electron dipole is close to 70% and even lower (68%). Back to 80% around noon.
