A new plasma-dynamo mechanism is proposed, with application to the outer region of the reversed-field pinch. The mechanism uses space-charge electric fields associated with particle transport to drive steady-state electrical currents which otherwise would resistively decay for lack of an externally applied electric field. The mechanism is suggested by recent observations during sustained discharges in the ZT-40M experiment.
