Title:

Observation of Plasma Toroidal Rotations Driven by the Electric Field Due to a Loss Ions

Date of publication:

Mar.1990

Key words:

plasma rotation, electric field, ambipolar flux, momentum balance, tokamak plasma

Abstract:

Plasma toroidal rotations not driven by the momentum input but by the electric field due to a loss of ions have been observed for the plasmas heated with perpendicular neutral beam injection. They are found to be increased in the counter direction to the plasma current as plasma ions are heated with ion cyclotron resonance frequency waves . The electric field derived from rotations are quantitatively consistent with those inferred from the ambipolarity of particle fluxes.
