Abstract
Small aspect ratio tokamak configurations are produced by adding a toroidal magnetic field to the rotamak. Configurations with toroidal fields ranging up to ~ 200 G at the magnetic axis are studied. Typical parameters are Itor ~ 2 kA, Bpoi ~ 50 G, q0 ~ 1-3, ne (peak) ~ 1019 m−3, Te ~ 12 eV, τp ~ 15 μs and τe ~ 5μs for an RF input power of ~ 40 kW. Most features of these configurations can be modelled by an MHD equilibrium code. The presence of the toroidal field is observed to have a significant influence on the rotating magnetic field current drive mechanism.Keywords
