keyword=Cavities and Striplines in RHRSCavities are showing signs of life in the HRS datastream.
This is run 4435 taken with a pulser trigger.
A lot of beam-off and some instability
Fig 1 = Beam current
Fig 2 = Correlation of Cavities vs Striplines.
The striplines have a very rough calibration in mm.
The cavities are raw ADC units.
The squarish donut is ok -- what you get for two triangle waveforms
with a phase that is a fraction of the period.
To get the plots this clean we cut on beam current.
But the doubling of the donut at points is still to be
understood. Possibly due to remaining beam instability
in the cut, or something (phase/gain) not yet adjusted.
