Characteristics of Internal Transport Barriers from the JET Optimized Shear Database
The general features of the Internal Transport Barriers obtained in the JET Optimized Shear regime are deduced from the analyses of a large database of discharges including the experiments performed with a mixture of Deuterium-Tritium ions. The coupled and complex spatio-temporal dynamics of the ITBs are studied from the radial profiles measurements of the thermal ion and electron temperatures. The spatial locations of t ITBs inside the plasma column are deduced from the radial derivatives of the plasma profiles. In particular, our analyses show that the radial positions of the ITB follow the same evolution for both the electron and ion temperature profiles.
