We investigate the scaling of the core energy transport with the::magnetic Lundquist number S in the reversed field pinch. We analyze for the first time: the electron temperature and thermal conductivity profiles and the dynamo magnetic fluctuations in a:wide-range, of stationary plasmas produced in the RFX device at plasma current ranging between 0.2 and 1.1 MA; When S increases we measure an improvement of core confinement associated with the strengthening of the internal electron temperature,- profiles gradient and with the decrease of magnetic turbulence. This shows that core energy transport;I is related with magnetic fluctuations and can be ameliorated in high S regimes.

Abstract

We investigate the scaling of the core energy transport with the::magnetic Lundquist number S in the reversed field pinch. We analyze for the first time: the electron temperature and thermal conductivity profiles and the dynamo magnetic fluctuations in a:wide-range, of stationary plasmas produced in the RFX device at plasma current ranging between 0.2 and 1.1 MA; When S increases we measure an improvement of core confinement associated with the strengthening of the internal electron temperature,- profiles gradient and with the decrease of magnetic turbulence. This shows that core energy transport;I is related with magnetic fluctuations and can be ameliorated in high S regimes.
