    Entry number 188648

    keyword=Spectra shifting

    We notice the same effect (except in reverse) as yesterday in the shift of the centroids of the missing-mass and missing-energy spectra.

    Run # Size of shift (MeV)
    1866 0
    1867 2 last run before accelerator down this morning
    1868 4 first run this shift
    1869 6
    1870 8 current run

    This, if it is indeed a problem in EPICS, should be fixed soon. If it is a hardware problem (magnetic field), it should be fixed right now.

    The current in the right dipole is holding steady (or at least the reading on the screen [662.3 A] is doing so).

    I'll call the run coordinator now.
