Abstract
Test-particle measurements of plasma cross-field ion transport show a dramatic change associated with the presence of sheared plasma flow pa rallel to a fixed magnetic field. Experimental conditions for enhanced transport are consistent with a simple model of shear flow instabilit y. Observed modulations in the tagging transfer function suggest a non linear model for the ion dynamics, and a spatially varying shift in th e ion gyrofrequency. The problem of determining electric fields from t est-particle measurements is posed.
