Recent theoretical studies have shown that a lower hybrid (LH) slow wave is a promising candidate for driving an additive parallel (~ poloidal) current in the outer region of the reversed field pinch (RFP) and thereby reducing magnetic fluctuations and particle and energy transport. To improve the theoretical modeling and to assist the experimental implementation of the scheme to the MST RFP, we are adapting the RFP geometry a generalized ray-tracing code GENRAY and a 3-D relativistic, bounce-averaged, Fokker-Planck code CQL3D. We eill use the new code package to study LH heating as well as current drive. LH heating could address issues such as the beta limit, pressure profile modifications, and Lundquist number scaling of magnetic fluctuations in the RFP.
