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..
