    keyword=Beam: oscillation in the halo reading

    we noticed that the halo rates are oscillating (some time by 30 %) with a
    period of 10 s as shown on the attched plot. It seems that these
    oscillations pause from time to time maybe each 15-20 mn.
    On the attached plot, the rates are not normailzed so we tried to see a
    correlation with the beam intensity. The beam instensity does fluctuate
    also but at a lot smaller scale (+-2.5 %) and the forms did not obviously
    track.

    we are going to look at a correlation with beam position..
