Shaping and internal structure in non-circular tokamaks
Abstract
Experiments on two non-circular tokamaks, TNT-A at Tokyo University and HYBTOK-1 at Nagoya University are presented. In TNT-A, active and passive control of the plasma shape has been carried out successfully. Plasma properties were studied in relation to the shaping field curvature. Diagnostics were made by Thomson-scattering experiments and by monitoring the poloidal field configuration inside and outside the plasma. An appropriate curvature of the shaping field was found to maintain a D-shaped stable plasma of moderate temperature of about 150 eV and relatively low safety factor of about 2 with the elongation ratio of about 1.5.
