Characteristics of the NASA Lewis Bumpy Torus plasma generated with high positive or negative applied potentials

Technical Report ·
OSTI ID:7216287
;
The toroidal ring of plasma contained in the NASA Lewis bumpy-torus superconducting magnet facility may be biased to positive or negative potentials approaching 50 kilovolts by applying direct-current voltages of the respective polarity to 12 or fewer of the midplane electrode rings. The electric fields which are responsible for heating the ions by E/B drift then point radially outward or inward. The low-frequency fluctuations below the ion cyclotron frequency appeared to be dominated by rotating spokes. (Author) (GRA)
