There is a self-consistent impurity transport theory that predicts an outward flow of impurities with neutral beam co-injection, and a greatly enhanced inward impurity transport with counter-injection. This theory has previously been shown to explain the experimental data quite well. The impurity flow reversal model has been applied to the TIBER II parameters to make a preliminary evaluation of the feasibility of using 500 keV neutral beams for impurity control in TIBER II. A secondary emphasis in this work is on determining the sensitivity of the results to the beam deposition and density profiles within the plasma.
