Models implemented in the methodological approach to design the initial STEP first wall contour

Davide Galassi, Kevin Henricus Annemarie Verhaegh, Filippo Bagnato, Dario Vaccaro

The official Spherical Tokamak for Energy Production mission aims to demonstrate the ability to generate net electricity from fusion with the STEP Prototype Power plant. One of the key technological and engineering challenges in fusion power plants is mana ...

Characterisation of detachment in the MAST-U Super-X divertor using multi-wavelength imaging of 2D atomic and molecular emission processes

Basil Duval, Artur Perek, Kevin Henricus Annemarie Verhaegh

In this work, we provide the first 2D spatially resolved description of radiative detachment in MAST-U Super-X L-mode divertor plasmas. The Super-X magnetic configuration was designed to achieve reduced heat- and particle loads at the divertor target compa ...

Plasma-molecular interactions generate molecular ions which react with the plasma and contribute to detachment through molecular activated recombination (MAR), reducing the ion target flux, and molecular activated dissociation (MAD), both of which create e ...

This paper shows first quantitative analysis of the detachment processes in the MAST Upgrade Super-X divertor (SXD). We identify an unprecedented impact of plasma-molecular interactions involving molecular ions (likely D2+ ), resulting in strong ion sinks ...

This work presents the use of a collisional-radiative model to infer plasma parameters from 2D emissivities of several deuterium Balmer lines. The emissivities were obtained by MANTIS, an absolutely calibrated, ten-camera imaging polychromator with

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 ...

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+

A novel hydrogenic spectroscopic technique for inferring the role of plasma-molecule interaction on power and particle balance during detached conditions

Basil Duval, Artur Perek, Kevin Henricus Annemarie Verhaegh, Mirko Wensing

Detachment, an important mechanism for reducing target heat deposition, is achieved through reductions in power, particle and momentum; which are induced through plasma-atom and plasma-molecule interactions. Experimental research in how those reactions pre ...

SOLPS-ITER validation with TCV L-mode discharges

Basil Duval, Patrick Blanchard, Holger Reimerdes, Christian Gabriel Theiler, Marcelo Baquero Ruiz, Artur Perek, Sophie Danielle Angelica Gorno, Claudia Colandrea, Marco Wischmeier, Cedric Kar-Wai Tsui, Kevin Henricus Annemarie Verhaegh, Mirko Wensing, Hugo De Oliveira, Filippo Bagnato, Lorenzo Martinelli

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 ...

Measurement of the 2D emission profiles of hydrogen and impurity ions in the TCV divertor

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

Plasma emission of hydrogen and impurities is measured with use of filtered camera imaging in TCV divertor. The measurement technique is discussed in detail including: selection choice of filters, the absolute calibration procedure and the tomographic inve ...
