Generation of a reversed field configuration without an applied magnetic field. Interim report
A rotating relativistic electron beam, charge- but not current-neutralized and exceeding the Alfven limit, has been propagated down a closed metal tube in the absence of an external guide field. The radial equilibrium is determined by the self-fields of the beam and the induced wall currents. The 100 nsec duration beam, upon leaving the system, induces plasma currents that maintain a field reversed configuration for 18 microseconds. (Author)
