Summary
The numerical modeling of the microwave power deposition in a plasma for waves that are launched from an arbitrary array of pyramidal horns will be described. The waves are modeled in three dimensions with geometrical optics assuming the plasma is cold, magneto-active and Maxwellian. The power absorption at the fundamental harmonic is calculated along those rays with warm plasma absorption formulas. A newly developed post-processor synthesizes power deposition profiles from these ray tracing results. Graphical output includes the power density as a function of the distance along the axis of the plasma and the physical or midplane radius, the z-integrated power density as a function of the midplane radius, and the cumulative power absorbed as a function of the midplane radius. Examples for ECRH in the TMX-U and the axisymmetric MFTF-B tandem mirror machines at LLNL will be presented.
