Advanced tokamak regimes obtained in ASDEX Upgrade, DIII-D, FT-U, JET, JT-60U, TCV and Tore Supra experiments are assessed both in terms of their fusion performance and capability for ultimately reaching steady-state using data from the international

Complete suppression of Pfirsch-Schlüter current in a toroidall= 3 stellarator

Autor: M. Wakatani, Y. Sato, M. Yokoyama, V. D. Pustovitov

Publikováno v: Nuclear Fusion. 40:1627-1633

Pfirsch-Schluter current (PSC) is an inherent property of a finite pressure toroidal plasma equilibrium in tokamaks and stellarators. However, it has been pointed out (V.D. Pustovitov, Nucl. Fusion 36 (1996) 583) that the PSC in a conventional stella

Negative shear effect on toroidal ion temperature gradient mode

Autor: M. Wakatani, J. Y. Kim

Publikováno v: Physics of Plasmas. 2:1012-1014

A study of the effect of negative shear on the toroidal ion temperature gradient mode is given. It is shown that the negative shear can give a substantial stabilizing effect on the mode when the safety factor q is small.

Confinement physics of non-axisymmetric torus

Publikováno v: AIP Conference Proceedings.

MHD stability of heliotron/torsatron type non‐axisymmetric torus is analyzed for current carrying plasmas. For highly peaked current profiles the current‐driven ideal internal kink mode is destabilized and sawtooth type oscillation is expected ev
