This OMFIT module runs the RABBIT code from a specified DIII-D shot. Inputs can either be automatically gathered from zipfit and MDS+, or manually assembeled from related modules.
RABBIT is capable of computing the NBI fast-ion distribution in real-time. It uses a simplified beam geometry to calculate the beam attenuation. Finite-orbit-width effects are taken into account by an orbit average of the beam deposition. The time-dependent solution of the Fokker-Planck equation (2D in velocity) is then calculated based on analytic expressions. This code currently takes about 25ms per time step, which is roughly a factor of 1000 faster than the more sophisticated NUBEAM code. Nevertheless, good agreement between both codes is found in a comprehensive benchmark.
