A mechanism for the excitation of linear and nonlinear ion-acoustic waves in a double plasma machine is suggested. A compressive ion density perturbation is interpreted in terms of 'klystron bunching' and a refractive ion density perturbation is inte

The propagation of an ion-acoustic soliton from a quiescent plasma region into a localized non-quiescent region ( Delta n/n mod soliton approximately= Delta /n mod noise) is experimentally examined. Several of the soliton properties are preserved alt

For pt.II see ibid., vol.26, no.6, p.799 (1984). The authors extent their study on grid excited ion-acoustic solitons to examine far field radiation characteristics. In particular, for propagation distances greater than any launching grid dimension,

Low-frequency noise (fci < f < fpi) excited by positively biased probes of various diameters near the magnets in a multidipole plasma device is investigated. It is concluded that the noise is due to the excitation of oblique ion-acoustic waves, i.e.,

A potential structure consisting of a negatively biased screen placed in front of a positively biased plate and inserted in the target chamber of a double-plasma machine is shown to be a reflector of ion-acoustic solitons. A simple model is proposed

Conditions which allow the formation of a stable ion phase-space vortex in a double plasma machine are reported. A high frequency propagating signal with a frequency ~ fpi/2 which cannot be associated with a dispersing Airy function is observed on th

Using a launching structure consisting of four large diameter hemispherical grids located at the corners of a square, it is observed that the amplitude of a resonantly produced soliton is greater than ten times the value of an individual soliton. Thi

Experiments on the expansion of a plasma into the wake region behind an object inserted in a flowing plasma are described. The dominant expansion mechanism that fills in the wake is determined to be a self‐similar expansion. Accelerated ions with a
