Theoretical study on the two electron-beam instability in a plasma waveguide
In relativistic plasma electronics, both theoretical and experimental studies indicate that the operating frequency of the mechanism of electron beam coupled with a TG mode wave in plasma filled waveguide can not be higher than either the plasma frequency or the beam plasma frequency. However, our recent investigation on the two stream instability (TSI) shows that the operating frequency may be much higher than plasma frequency or the beam plasma frequency.
