Towards self-consistent plasma modelisation in presence of Neoclassical Tearing Mode and sawteeth: effects on transport coefficients

The neoclassical tearing modes (NTM) increase the effective heat and particle radial transport inside the plasma, leading to a flattening of the electron and ion temperature and density profiles at a given location depending on the safety factor q ration ...
