    keyword=Beam Energy Fluctuating

    The first plot below is screen shot of current beam energy. It's drifting on the level of 1MeV. The Hall A energy lock is ON, therefore the number is not supposed to be drifting.

    As a comparison , the second plot is the beam energy read back in last production period (constantly stable for days).
