A multi-ion species confinement analysis code (MICADO) has been developed for the PLT ICRF and Ion Bernstein Wave (IBW) heating experiments. For ICRF heating, the power is assumed to be absorbed by a minority ion species whose velocity distribution is determined using a one-dimensional velocity space diffusion equation in a multi-ion species background plasma. For the IBW heating, the power deposition profile is obtained from a ray-tracing calculation. The power is absorbed by the perpendicular-component of the heated ion species which produces an effective T/sub perpendicular/. The power flow into electrons and various ion species (including impurity ions) are calculated in each spatial grid. The self-consistent one-dimensional ion energy transport equations are solved for each ion species using an iterative procedure. The modeling code is found to agree well with many of the ion heating features observed in the PLT ICRF and IBW heating experiments.
