Abstract

A qualitative model is given to describe the redistribution of ICRF-heated minority ions at sawtooth crashes in tokamak plasmas. A crucial feature of the model is that it takes into account profile broadening effects due to the finite width of the ICRF-heated particle orbits. Predictions of the model are compared and found to be in agreement with numerical simulations as well as with experimental results from JET.
