Abstract

The fluctuating flow velocity and its spatial structure in the outer region of the reversed field pinch were measured to determine the dynamics responsible for the dynamo. The relation between the measured dynamo electromotive force and the measured plasma current was examined. The relevant fluctuating quantity of the dynamo were correlated with each of the magnetic modes resolved by a toroidal array of 32 magnetic pickup coils, yielding components of mode number n = 1 to 15.
