Radoation and confinement properties of impurity seeded discharges in the reversed field pinch RFX

摘要

The compatibility of the reversed field pinch configuration with a highly radiative mantle at the edge has been proven by injecting neon into high density FRX plasmas: with respect to ordinary non-seeded discharges, energy confinement only marginally deteriorates, and the convection losses onto the plasma facing wall are reduced.
