Phys. Rev. E 61, 4431–4440 (2000)Effectiveness of rf phase modulation for increasing bunch length in electron storage ringsReceived 25 March 1999; published in the issue dated April 2000 Aiming at increasing the apparent bunch length and hence the beam lifetime in electron storage rings, rf phase modulation near one parametric resonance has been experimentally investigated. Since the possible benefit of this technique depends greatly on the ring parameters, we studied the effect of such a modulation for different rf parameters on the longitudinal emittance. Theoretical predictions and results of simulations are compared and discussed. It is shown that synchrotron radiation tends to spoil the parametric resonance. In particular, a criterion for island survival has been found. © 2000 The American Physical Society URL:
