Abstract
The radial electric field is driven to positive value by off-axis seco nd harmonic electron cyclotron heating (ECH) in the Compact Helical Sy stem [Plasma Physics and Controlled Nuclear Fusion Research 1988, Nice (International Atomic Energy Agency, Vienna; 1989), Vol. II, p. 411]. The observed positive electric field is associated with the outward p article flux enhanced with ECH. The enhanced particle flux triggered b y the production of the electrons accelerated perpendicularly to the m agnetic field with ECH results in the change of the electric field.
