MICROWAVE EMISSION FROM NONEQUILIBRIUM PLASMAS IN INSB SUBJECT TO MAGNETIC FIELDS,

Abstract

The paper draws together a large amount of experimental information obtained by others as well as the author. Out of the maze of conflicting, at best, and contradictory, at worst, results, one set of consistent characteristics of the emission and its associated phenomena results. The reconciliation is obtained by means of a theory for the spatial distribution of plasmas during emission. It shows why some samples emit preferentially for B parallel to E, others for B perpendicular to E, and still others for intermediate orientation. The theory also clarifies the various observed threshold dependencies. The conflicting results concerning the spectral characteristics of the emission are attributed to faulty experimental techniques. Thus four characteristics of the emission and its associated phenomena are clearly described qualitatively, the spectrum, the polar dependencies, the sometimes attendant MHz resistance oscillations, and the threshold dependencies on E and B.
