Reversed magnetic shear operation with ICRF minority heating on Tore Supra

mid-radius increases from 0.5 MA/m 2 to 1.2 MA/m 2 and becomes higher than the central value which is almost constant (less than 1 MA/m 2 ). In the case 2, an opposite behaviour of the current diffusion is observed. The resistive current rapidly diffuses to the core region: the central value rises from 0.6 MA/m 2 to 1.8 MA/m 2 , exceeding the mid-radius value which weakly increases.
