Methods of RF Current Drive
Authors: Nathaniel J. Fisch
Abstract:
Radio frequency waves can penetrate thermonuclear plasmas, depositing momentum and energy
with great selectively: in select resonant ions or electrons, in select resonant regions, and with select
momentum. When these waves are injected asymmetrically with respect to the toroidal direction
in tokamaks, they can drive toroidal electric current. The advantage of driving this current by
waves is that a tokamak reactor might then be operated in the steady state. This paper will review
the elementary processes of wave-particle interactions in plasma that underlie the current-drive
effect.
