NBI optimization on SMART and implications for scenario development
Mario Ludovico Podesta, Francesca Maria Poli
The SMall Aspect Ratio Tokamak (SMART) under commissioning at the University of Seville, Spain, aims to explore confinement properties and possible advantages in confinement for compact/spherical tokamaks operating at negative vs. positive triangularity. T ...
Bristol2024Investigating the impact of the molecular charge-exchange rate on detached SOLPS-ITER simulations
Basil Duval, Holger Reimerdes, Christian Gabriel Theiler, Kevin Henricus Annemarie Verhaegh
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 ...
IOP Publishing Ltd2023Full-discharge simulation and optimization with the RAPTOR code, from present tokamaks to ITER and DEMO
Tokamak devices aim to magnetically confine a hydrogen plasma at sufficiently high pressure to achieve net energy production from nuclear fusion of light isotopes. Predictive modeling and optimization is crucial for reliable operation of tokamak reactors, ...
EPFL2023Numerical simulations of gas puff imaging using a multi-component model of the neutral-plasma interaction in the tokamak boundary
A three-dimensional simulation of gas puff imaging (GPI) diagnostics is carried out by using a self-consistent multi-component model of the neutral-plasma interaction. The simulation, based on the drift-reduced Braginskii model for the plasma and a kinetic ...
AIP Publishing2022Physics and applications of three-ion ICRF scenarios for fusion research
Henri Weisen, Javier García Hernández, Mikhail Maslov, Samuele Mazzi
This paper summarizes the physical principles behind the novel three-ion scenarios using radio frequency waves in the ion cyclotron range of frequencies (ICRF). We discuss how to transform mode conversion electron heating into a new flexible ICRF technique ...
AMER INST PHYSICS2021Model-based optimization of magnetic control in the TCV tokamak: design and experiments
Thermonuclear controlled fusion is a promising answer to the current energy and climate issues, providing a safe carbon-free source of energy which is virtually inexhaustible. In magnetic confinement thermonuclear fusion based on tokamak reactors, hydrogen ...
EPFL2021Development of free-boundary equilibrium and transport solvers for simulation and real-time interpretation of tokamak experiments
To exploit fusion as a source of energy, a hot and dense confined plasma is needed. This is
achieved in tokamaks by actively controlling the plasma state meaning shape, position and
internal kinetic profiles. This thesis addresses two topics: the developme ...
EPFL2021Mixed hydrogen-deuterium plasmas on JET ILW
A study of mixed hydrogen-deuterium H-mode plasmas has been carried out in JET-ILW to strengthen the physics basis for extrapolations to JET D-T operation and to support the development of strategies for isotope ratio control in future experiments. Variati ...
2020Tokamak Edge Plasma Turbulence Interaction with Magnetic X-Point in 3D Global Simulations
Turbulence in the edge plasma of a tokamak is a key actor in the determination of the confinement properties. The divertor configuration seems to be beneficial for confinement, suggesting an effect on turbulence of the particular magnetic geometry introduc ...
