Abstract
The co-excitation of plasma normal modes and a pseudo-mode (burst-ion signal) in a beam–plasma system containing a stationary ion beam is experimentally investigated in a double-plasma device. The ion waves are excited by applying a ramp voltage to an excitation grid (rather than separation grid) immersed in the beam–plasma system. By studying the dependence of the phase velocities of the excited signals on the characteristics of the ramp signal and on the ion-beam velocity, four kinds of coexisting waves can be identified, i.e., a fast and a slow ion-beam modes, an ion-acoustic mode, and the burst-ion signal, respectively.
