The fusion reaction rate and, thus, the energy production is strongly dependent on ion temperature and density. Therefore, optimizing these quantities is essential when designing a fusion reactor. However, if the plasma is hot close to the separatrix, lot of energetic particles will escape from the plasma, causing a threat to the first wall. Therefore, the ideal plasma profiles would have a broad hot and dense region around the plasma core, and a cool edge. One way to maintain this kind of profiles is by creating a so-called Internal Transport Barrier (ITB). Traditionally, ITBs are observed in advanced scenario plasmas, characterized by a reversed magnetic shear in the plasma center. Such a reversed q-profile can be created by a low or vanishing toroidal current in the plasma center, which decreases the poloidal magnetic field and, consequently, increases the widths of fast particle orbits.
