A high-resolution polarimetry-interferometry system was used to measure the current profile and core magnetic field fluctuation amplitudes in a reversed-field pinch. The core magnetic field fluctuation amplitude was observed to increase at a sawtooth crash. It was shown that the parallel current density increases in the outer region of the plasma during auxiliary pulsed parallel current drive. It was found that the current density also increases in the core, relative to standard plasmas.
