Multi-machine benchmark of the self-consistent 1D scrape-off layer model DIV1D from stagnation point to target with SOLPS-ITER
This paper extends a 1D dynamic physics-based model of the scrape-off layer (SOL) plasma, DIV1D, to include the core SOL and possibly a second target. The extended model is benchmarked on 1D mapped SOLPS-ITER simulations to find input settings for DIV1D th ...
Bristol2024Validation of short-pulse reflectometry turbulence measurements with a synthetic diagnostic
Stefano Coda, Stephan Brunner, Oleg Krutkin, Umesh Kumar, Mackenzie Peter-Fulford Van Rossem, Samuele Mazzi
Experimental measurements of the turbulence amplitude utilizing a short pulse reflectometry method are presented. Two discharges with shaped plasma possessing opposite signs of triangularity are considered and a higher turbulence amplitude is found in the ...
Bristol2024Optimization of X-mode electron cyclotron current drive in high-electron-temperature plasma in the EAST tokamak
Joan Decker, Chunmin Zhang, Fang Liu
A discharge with electron temperature up to 14 keV has been achieved in EAST. Analysis of the electron cyclotron current drive (ECCD) efficiency at high electron temperature under EAST parameters is presented using C3PO/LUKE code. Simulation results show t ...
IOP Publishing Ltd2023Characterisation 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 ...
IOP Publishing Ltd2023Experimental and numerical investigations of electron transport enhancement by electron-cyclotron plasma-wave interaction in tokamaks
Stefano Coda, Laurent Villard, Laurie Porte, Joan Decker, Giovanni Di Giannatale, Aylwin Iantchenko, Jean Arthur Cazabonne
Energy transfer from electron-cyclotron (EC) waves to the plasma is being routinely used in tokamaks to heat and drive current through the electron channel. Technical applications such as magnetohydrodynamic mode mitigation require power deposition with a ...
IOP Publishing Ltd2023Validation of GBS plasma turbulence simulation of the TJ-K stellarator
Paolo Ricci, Joaquim Loizu Cisquella
We present a validation of a three-dimensional, two-fluid simulation of plasma turbulence in the TJ-K stellarator, a low temperature plasma experiment ideally suited for turbulence measurements. The simulation is carried out by the GBS code, recently adapt ...
IOP Publishing Ltd2023An experimental and computational study of tokamak plasma turbulence
Turbulence driven by small-scale instabilities results in strong heat and particle transport, which significantly shortens the confinement time and prevents the formation of a self-sustained plasma reaction in magnetic confinement devices. Control and poss ...
EPFL2023Modelling of nonneutral plasmas trapped by electric and magnetic fields relevant to gyrotron electron guns
Gyrotrons are a class of high-power vacuum-electronics microwave sources, which are envisioned to play an important role in the domain of magnetically confined fusion plasmas. Indeed, only gyrotrons are capable of producing continuous electromagnetic waves ...
EPFL2023Development of algorithms for the end-end system simulation and performance analysis for a high-frequency magnetic diagnostic system: Application to ITER, JET and TCV
An innovative and very detailed end-to-end system modelling tool has been developed and applied to test on simulated data the actual measurement capabilities of any generic high frequency (HF) magnetic diagnostic systems. The main goal of this rather compl ...
ELSEVIER SCIENCE SA2022A fast-moving Langmuir probe array for the divertor of the Tokamak à Configuration Variable
In next step tokamaks such as ITER and future fusion power plants, wall materials will be subjected to considerably higher heat and particle fluxes than in present-day machines. Maintaining plasma facing components in good condition and simultaneously assu ...
