Abstract
An experimental study of the injection of a intense relativistic electron beam into a plasma confined in a toroidal magnetic field is described. An increase in toroidal current after beam injection was observed and is argued to be the result of both beam-induced and additional Ohmic-heating-driven plasma currents. Typical current-drive efficiencies (beam net current to injected-beam current) of (10-30)% were observed.Keywords
