An optimized upper divertor with divertor-coils to study enhanced divertor configurations in ASDEX Upgrade [PDF]

Fusion Engineering and Design, 2017
Abstract A new upper divertor with in-vessel coils to investigate ‘advanced’ magnetic configurations will be installed in ASDEX Upgrade. ‘Advanced’ magnetic configurations are part of a risk mitigation strategy should the conventional divertor configuration approach not be applicable for future fusion reactors.

Transport Properties in Nontwist Area-Preserving Maps [PDF]

, 2009
Nontwist systems, common in the dynamical descriptions of fluids and plasmas, possess a shearless curve with a concomitant transport barrier that eliminates or reduces chaotic transport, even after its breakdown.

Power Deposition on Tokamak Plasma-Facing Components [PDF]

, 2016
The SMARDDA software library is used to model plasma interaction with complex engineered surfaces. A simple flux-tube model of power deposition necessitates the following of magnetic fieldlines until they meet geometry taken from a CAD (Computer Aided ...

Scoping the characteristics and benefits of a connected double-null configuration for power exhaust in EU-DEMO

Nuclear Materials and Energy, 2021
A double-null configuration is being considered for the EU-DEMO, due to its potential benefits for power exhaust arising from the use of two active divertors and magnetically disconnected low- and high-field sides.

Taming the Heat Flux Problem: Advanced Divertors Towards Fusion Power [PDF]

, 2016
The next generation fusion machines are likely to face enormous heat exhaust problems. In addition to summarizing major issues and physical processes connected with these problems, we discuss how advanced divertors, obtained by modifying the local ...

Measurements and modeling of type-I and type-II ELMs heat flux to the DIII-D divertor

Nuclear Fusion, 2023
Type-I and type-II edge-localized-modes (ELMs) heat flux profiles measured at the DIII-D divertor feature a peak in the vicinity of the strike-point and a plateau in the scrape-off-layer (SOL), which extends to the first wall.

A Review of Recent Developments in Atomic Processes for Divertors and Edge Plasmas

, 1995
The most promising concepts for power and particle control in tokamaks and other fusion experiments rely upon atomic processes to transfer the power and momentum from the edge plasma to the plasma chamber walls. This places a new emphasis on processes at
