Abstract
When an external RF field is applied to an ion beam plasma system, ion-ion instability is suppressed at f/fii\\gtrsim1, where f and fii are the frequency of the external RF field and the peak frequency of the instability, respectively. It is also observed that the time-averaged energy distribution function of the ion beam broadens when the instability is suppressed. In order to investigate the cause of this broadening, time-resolved energy distribution functions of ions are measured with a boxcar integrator. As a result, it is found that the energy distribution functions periodically change with the external RF field and the above broadening is apparently caused by the time-averaging of the energy distribution functions.
