Abstract :
We report results of calculations and measurements relating RF phase noise to longitudinal motion of a stored beam. Treating the beam as a noise driven coupled oscillator system, we have made calculations to determine what coupled bunch synchrotron oscillation amplitudes result from RF phase noise. Measurements have also been carried out at CESR of phase noise in the RF system and coupled bunch synchrotron oscillation amplitudes. We also consider the impact of this noise on the dynamic range of a longitudinal feedback system
