Abstract

ONETWO is a one-and-a-half-dimensional, time-dependent computer code for modeling plasma transport in tokamaks. Both circular and noncircular cross-section plasmas, including doublets, can be modeled along with currents in field-shaping coils. Electrons, several species of ions, and two species of neutrals may be considered simultaneously. The electrons and ions are treated as fluids, while the neutrals are treated kinetically. Neoclassical and several anomalous transport models are available. Important physical processes that produce sources and sinks of particles and energy are also considered, including ohmic heating, electron-ion energy exchange, radiation, neutral transport (and gas puffing), neutral beam heating, RF heating, pellet fueling, and fusion.
