Evaluation of DIII-D plasmas for Future Measurements of the Driven Current Density in the DIII-D High Field Side Lower Hybrid Experiment [PDF]

EPJ Web of Conferences
High field side (HFS) lower hybrid current drive (LHCD) is a promising method for efficiently driving off-axis current in steady state tokamak power plants. The first test of this technology is underway at the DIII-D tokamak.

Evolution of energy confinement physics and most probable compact ignition test device in magnetic fusion

AAPPS Bulletin
The variation of edge confinement modes such as L-mode, H-mode, QH-mode, and I-mode and transitions between these modes in toroidal devices is attributed to interplay between turbulent inflow plasmas from divertor and outflow plasmas from the edge in ...

Balancing physics priors and data for disruption prediction in future tokamaks

Nuclear Fusion
Disruption remains a major barrier to the safe, sustained operation of tokamaks. Although current understanding of disruption physics is broadly valid across existing tokamaks, it cannot provide accurate disruption prediction rules.

Analysis of high-field side plasma instabilities in tokamak edge

Nuclear Materials and Energy
Balanced double-null configurations are of general interest for boundary plasma physics, and they have been proposed for some future designs. Experimental observations demonstrate absence of plasma fluctuations in tokamak high-field side scrape-off layer

Runaway electron mitigation by 3D fields application in ASDEX Upgrade, COMPASS, and RFX-mod

Frontiers in Physics
Disruption-generated runaway electron (RE) beams represent a potentially severe threat for tokamak plasma-facing components. Application of properly designed 3D fields can act as a mitigation mechanism, as recently investigated in ASDEX Upgrade (AUG) and
