13. Reduction of the ion drive and rho*(theta) scaling of the neoclassical tearing mode.

Author

Poli E, Peeters AG, Bergmann A, Günter S, and Pinches SD

Abstract

In the theoretical description of the neoclassical tearing mode it is usually assumed that the ion banana width w(b) is much smaller than the island width W. This assumption is questionable at least for the island size at the mode onset. We show that a significant fraction of the (ion) bootstrap current survives inside the island when w(b) is comparable to W. This effect also leads to a linear scaling of beta(onset)theta with the normalized ion poloidal gyroradius rho*(theta), in agreement with the experimental results of ASDEX Upgrade.

14. Reaching high poloidal beta at Greenwald density with internal transport barrier close to full noninductive current drive.

Author

Abstract

In the ASDEX Upgrade tokamak, high poloidal beta up to beta(pol) = 3 at the Greenwald density with H-mode confinement has been reached. Because of the high beta, the plasma current is driven almost fully noninductively, consisting of 51% bootstrap and 43% neutral beam driven current. To reach these conditions the discharge is operated at low plasma current ( I(P) = 400 kA) and high neutral beam heating power ( P(NBI) = 10 MW). The discharge combines an edge (H mode) and internal transport barrier at high densities without confinement-limiting MHD activities. The extrapolation to higher plasma currents may offer a promising way for an advanced scenario based fusion reactor.
