Electron gyroscale fluctuation measurements in National Spherical Torus Experiment H-mode plasmas [PDF]

, 2019
A collective scattering system has measured electron gyroscale fluctuations in National Spherical Torus Experiment [M. Ono et al., Nucl. Fusion 40, 557 (2000)] H-mode plasmas to investigate electron temperature gradient (ETG) turbulence. Observations and

Performance of a liquid Sn divertor target during ASDEX upgrade L-mode and H-mode operation

Nuclear Materials and Energy, 2023
One of the ways to extend the lifetime of the divertor for DEMO could be to replace the solid tungsten plasma-facing components with liquid tin (Sn) confined in a tungsten capillary porous structure (CPS). Testing a CPS in a divertor plasma configuration

The H-Mode of ASDEX

Nuclear Fusion, 1989
The paper is a review of investigations of the H-mode on ASDEX performed since its discovery in 1982. The topics discussed are: (1) the development of the plasma profiles, with steep gradients in the edge region and flat profiles in the bulk plasma, (2) the MHD properties resulting from the profile changes, including an extensive stability analysis, (3)

I-mode studies at ASDEX Upgrade: L-I and I-H transitions, pedestal and confinement properties [PDF]

, 2016
The I-mode is a plasma regime obtained when the usual L-H power threshold is high, e.g. with unfavourable ion B ∇ direction. It is characterised by the development of a temperature pedestal while the density remains roughly as in the L-mode ...

Solitary magnetic perturbations at the ELM onset [PDF]

, 2012
Edge localised modes (ELMs) allow maintaining sufficient purity of tokamak H-mode plasmas and thus enable stationary H-mode. On the other hand in a future device ELMs may cause divertor power flux densities far in excess of tolerable material limits. The
