Journal ArticleDOI
Scintillator based detector for fast-ion losses induced by magnetohydrodynamic instabilities in the ASDEX upgrade tokamak.
TL;DR: The design of the scintillator probe, the new technique used to analyze the data through spectrograms will be described, as well as the diagnosis prospects of this method for ITER.

TL;DR: In this paper, a modified divertor configuration for ASDEX upgrade, allowing operation at higher triangularity, and with a changed neutral beam injection (NBI) system, for a more tangential, off-axis beam deposition.
Journal ArticleDOI
Experimental Study of Trapped-Electron-Mode Properties in Tokamaks: Threshold and Stabilization by Collisions
TL;DR: Experiments using modulated electron cyclotron heating in the ASDEX Upgrade tokamak demonstrate explicitly the existence of a threshold in normalized gradient and stabilization by collisions, supported by linear gyrokinetic calculations.
Journal ArticleDOI
Tokamak operation with high-Z plasma facing components

TL;DR: In this article, a simple model based on dimensionless quantities for fuel and high-Z ion sources and transport to describe the high Z concentration in the plasma core is introduced, and the impurity release and further transport is factorized into the sputtering yield, the relative pedestal penetration probability and a core confinement enhancement factor.
