Ion cyclotron resonance for fast magnetosonic waves in small tokamaks

The absorption of fast magnetosonic waves in a small-size tokamak has been studied under the multiple cyclotron resonance for bulk ions and under the fundamental resonance for minority ions. The small plasma radius is assumed to be less than or equal to, in the order of magnitude, the transverse wav...
