Abstract
A rotating relativistic beam of energy 500 keV and current 20-40 kA is injected into a preformed plasma of density np between 1012 and 1014 cm-3. It is observed that optimum coupling of beam energy to the plasma occurs at npnb, where nb is the beam density. The peak plasma temperature is about 1 keV. The heated plasma undergoes radial oscillations characteristic of the magnetosonic mode. The results are interpreted with a new theoretical model. © 1975 The American Physical Society.
