We present the results of the first successful experiments aimed to control in a quasistationary way the magnetic fluctuation dynamics in a reversed field pinch (RFP) device. This is done by the application of an oscillating poloidal electric field to the plasma edge. Although the additional power input is negligible, a stationary positive effect on the electron temperature is obtained. Temperature increases up to 50% over the standard values. This experiment demonstrates that in principle a stationary current profile and magnetic fluctuation control technique is feasible in the RFP.

Abstract
We present the results of the first successful experiments aimed to control in a quasistationary way the magnetic fluctuation dynamics in a reversed field pinch (RFP) device. This is done by the application of an oscillating poloidal electric field to the plasma edge. Although the additional power input is negligible, a stationary positive effect on the electron temperature is obtained. Temperature increases up to 50% over the standard values. This experiment demonstrates that in principle a stationary current profile and magnetic fluctuation control technique is feasible in the RFP.File in questo prodotto:
