摘要:
By inserting a grid in a beam‐generated plasma column, single waves can be produced as a result of the beam‐plasma instability exciting a finite‐length cavity mode. The oscillation frequency is found to increase with beam velocity, in contrast to the frequency‐velocity relationship of the wave with the maximum growth rate. The nonlinear evolution of the beam‐generated wave and satellites due to a test wave are observed.
