Ion temperature, heating and scaling relations at the Extrap-T1 reversed-field pinch

Abstract

Investigations of the temperatures of the in situ impurity ions , , , and have been performed at the Extrap-T1 reversed-field pinch (RFP) via measurements of the Doppler broadening of emission lines in the near-UV wavelength region. Ion temperatures of the high ionization stages are found to be of the order of the electron temperature.
