Abstract.  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.
