    keyword=Shift summary

    08:00 run 1800 underway
    RF problems around noon turn out to be short lived
    Continuing problems with script to check FPP and calorimeter giving false alarms
    ~13:00 notice a shift in the calorimeter missing energy spectrum. Closer inspection shows gradual shift over 2-3 runs with large shifts coming at run 1806.
    (See halog 53344)
    Suspect that effect may be from stray field from the right dipole. This is also probably related to the FFP and calorimeter script alarm of earlier (be careful what you call a false alarm)
    On-line analysis of run 1808 verifies the above suspision. Emiss spectrum is shifting back to where it was before the magnet was ramped up. Ramp up of dipole started about 11:30. Max current reached at about 13:00. Ramp down started 14:27. (see halog entries marked "magnet tests")
