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

Holger Reimerdes, Marco Wischmeier, Mirko Wensing

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. Using systematic parameter scans in fluid ...

Initial TCV operation with a baffled divertor

Ambrogio Fasoli, Holger Reimerdes, Basil Duval, Jean-Marc Moret, Duccio Testa, Patrick Blanchard, Christian Gabriel Theiler, Umar Sheikh, Matthieu Toussaint, Marcelo Baquero Ruiz

The Tokamak à Configuration Variable (TCV) tokamak is in the midst of an upgrade to further its capability to investigate conventional and alternative divertor configurations. To that end, modular and removable gas baffles have been installed to decrease t ...

SOLPS-ITER validation with TCV L-mode discharges

Basil Duval, Patrick Blanchard, Holger Reimerdes, Christian Gabriel Theiler, Marco Wischmeier, Marcelo Baquero Ruiz, Artur Perek, Cedric Kar-Wai Tsui, Kevin Henricus Annemarie Verhaegh, Mirko Wensing

This work presents a quantitative test of SOLPS-ITER simulations against tokamak a configuration variable (TCV) L-mode experiments. These simulations account for drifts, currents, kinetic neutrals, and carbon impurities providing the most complete edge tra ...

Preliminary analysis of alternative divertors for DEMO

Paolo Ricci, Holger Reimerdes, Marco Wischmeier, Fabio Riva, Mirko Wensing

A physics and engineering analysis of alternative divertor configurations is carried out by examining benefits and problems by comparing the baseline single null solution with a Snowflake, an X- and a Super-X divertor. It is observed that alternative confi ...

The role of plasma-molecule interactions on power and particle balance during detachment on the TCV tokamak

Basil Duval, Christian Gabriel Theiler, Artur Perek, Kevin Henricus Annemarie Verhaegh, Mirko Wensing

This paper shows experimental results from the TCV tokamak that indicate plasma-molecule interactions involving D2+

IOP Publishing Ltd2021

A study of the influence of plasma-molecule interactions on particle balance during detachment

Basil Duval, Christian Gabriel Theiler, Kevin Henricus Annemarie Verhaegh, Artur Perek, Mirko Wensing

In this work we provide experimental insights into the impact of plasma-molecule interactions on the target ion flux decrease during divertor detachment achieved through a core density ramp in the TCV tokamak. Our improved analysis of the hydrogen Balmer s ...

Drift-related transport and plasma-neutral interaction in the TCV divertor

Mirko Wensing

Thermonuclear fusion of light atoms is the primary energy source of stars, such as our Sun, that led to the emergence of life on Earth. However, its economic exploitation as a virtually unlimited and clean energy source is yet to be developed. One of the m ...

Comparison of high density and nitrogen seeded detachment using SOLPS-ITER simulations of the tokamak a configuration variable

Basil Duval, Holger Reimerdes, Christian Gabriel Theiler, Kevin Henricus Annemarie Verhaegh, Mirko Wensing, Hugo De Oliveira, Lorenzo Martinelli

First of a kind SOLPS-ITER simulations on tokamak a configuration variable (TCV) that include nitrogen have been performed to model recent nitrogen seeded detachment experiments. Based on spectroscopic measurements, a nitrogen recycling coefficient R-p(N) ...

Numerical investigation of optimal divertor gas baffle closure on TCV

Stefano Coda, Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Davide Galassi, Mirko Wensing

A first set of divertor gas baffles has recently been installed in the TCV tokamak. In order to explore the physics determining the benefits and limitations of divertor baffling and to guide the design of a possible second generation of baffles, the effect ...

Separating the roles of magnetic topology and neutral trapping in modifying the detachment threshold for TCV

Christian Gabriel Theiler, Kevin Henricus Annemarie Verhaegh, Mirko Wensing

Total flux expansion, a divertor magnetic topology design choice embodied in the Super-X divertor, is predicted through simple analytic models and SOLPS calculations to reduce the plasma and impurity density detachment thresholds as the outer divertor sepa ...
