Self-consistent Calculations of the Power Deposition and Velocity Distribution during Icrh including Finite Orbit Widths, Spatial Rf- Induced Drift and Diffusion

SELF-CONSISTENT CALCULATIONS OF THE POWER DEPOSITION AND VELOCITY DISTRIBUTION DURING ICRH INCLUDING FINITE ORBIT WIDTHS, SPATIAL RF-INDUCED DRIFT AND DIFFUSION. Self-consistent calculations of ICRH for toroidally directed wave spectrum have revealed the importance of including finite orbit width and RF-induced spatial transport. This is in particular important for heating at higher harmonics in which case the cyclotron absorption depends strongly on the details of the distribution function.
