Influence of the relative position of ICRH resonant layer on the internal kink mode stability

The problem of the internal kink mode stabilisation by ion cyclotron resonance heating (ICRH) driven fast particles has been the subject of several studies over the last years. The internal kink mode is sup-posed to be responsible for the sawtooth instability, which play an important role on the central plasma stability. The control of sawtooth assumes then a crucial importance, with one of the most promisin
