Stabilization of ion temperature gradient mode by small-scale zonal flows

Li, J.; Kishimoto, Yasuaki

Physics of Plasmas, 10(3), p.683 - 688, 2003/03

 Times Cited Count:14 Percentile:41.52(Physics, Fluids & Plasmas)

Interaction between large-scale turbulence and small-scale sheared flows isa new issue in magnetized plasmas. In this work, the key interactionmechanism is explored by sampling the large-scale ion temperature gradient (ITG) mode and the small-scale zonal flows driven by the electron temperature gradient (ETG) turbulence. It is analytically found that the small-scale zonal flows lead to a radially non-local mode coupling of ITG fluctuations.

Diagnostics for fusion plasma control in JT-60U

Kawano, Yasunori; JT-60 Team

Proceedings of 30th EPS Conference on Controlled Fusion and Plasma Physics (CD-ROM), 4 Pages, 2003/00

Diagnostics play essential roles both in understanding of the plasma physics and in control of the plasma itself. JT-60U has plenty of developments and thus experiences in concepts of the real-time feedback control. The parameters concerned are averaged electron density, neutron emission rate, plasma stored energy, central electron temperature, temperature gradient, temperature fluctuations, current density profile, plasma radiation, outer gap distance, neutral gas pressure, etc., and those combinations. In JT-60U, production of high-performance fusion plasmas and their sustainment owed to such the real-time feedback control. In this paper, the overview of diagnostics equipped for the real-time feedback control in JT-60U is presented.
