The code TORIC solves the finite Larmor radius wave equations in the ion cyclotron frequency range in arbitrary axisymmetric toroidal geometry. The model describes the compressional and torsional Alfvén waves and ion Bernstein waves excited by mode conversion near the first ion cyclotron harmonic. In the ion response the broadening of the absorption regions due to the finite width of the cyclotron resonance of individual ions in toroidal geometry is taken into account. The parallel component of the wave electric field is evaluated on the same footing as the transverse ones; the response of the electrons includes Landau damping, Transit Time damping and the mixed term.
As an option the Order Reduction Algorithm is implemented, providing fast, yet accurate evaluation of the power deposition profiles in toroidal geometry. The report describes the model and its numerical implementation, and provides the information needed to use the code.
