Times Cited Count：0 Percentile：0.01(Physics, Fluids & Plasmas)This paper describes the present status of the JT-60SA (JT-60 Super Advanced) project which has been implemented jointly by Europe and Japan since 2007. Design of the main tokamak components were completed in late 2008, where all the scientific missions are preserved to contribute to ITER and DEMO reactors. The construction of the JT-60SA has began with procurement activities for the superconducting magnet systems, vacuum vessel, in-vessel components and other components under the relevant procurement arrangements between the implementing agencies of JAEA (Japan Atomic Energy Agency) in Japan and Fusion for Energy in Europe. Designs and developments of the auxiliary heating systems for JT-60SA have been progressed at JAEA so as to provide the total injection power of 41 MW for 100s.

Times Cited Count：4 Percentile：16.39(Physics, Fluids & Plasmas)Stability of magnetohydrodynamic (MHD) waves subject to Alfv
n and sound resonances and small resistivity at a conductive wall is formally discussed in terms of wave energy (or, more precisely, wave action). Negative energy wave, which may exist in the presence of mean flow, is shown to be destabilized by the resistive wall, where its growth rate is characterized by the energy dissipation rate. The effect of resonance is examined as well based on a recent knowledge of wave energy for Alfvn and sound continuum modes. Resonant coupling between an eigenmode and a continuum mode having the same sign of energy results in phase mixing (or continuum) damping. In contrast, if their signs are opposite, such resonance triggers an instability.

JT-60 completed 24-year operation towards the construction of the next superconducting device JT-60SA. In this presentation, recent results of JT-60 for establishment of advanced tokamak concept for ITER and DEMO (i.e. status of development of plasmas with high beta, high confinement, high bootstrap-current fraction and high radiation fraction, as well as development of advanced diagnostics and high heating power technology) will be presented. Status of JT-60SA programme is also reported.
