Phys. Rev. Lett. 91, 205004 (2003) [4 pages]Current Drive in a Ponderomotive Potential with Sign ReversalSee Also: Erratum
See accompanying Physics Focus Noninductive current drive can be accomplished through ponderomotive forces with high efficiency when the potential changes sign over the interaction region. The effect, which operates somewhat like a Maxwell demon, can be practiced upon both ions and electrons. The current-drive efficiencies, in principle, might be higher than those possible with conventional rf current-drive techniques. It remains, however, for us to identify how the effect might be implemented in a magnetic fusion device in a practical manner. © 2003 The American Physical Society URL:
