Experimental study and interpretative modelling of the Power Exhaust in Configurations with Multiple X-Points in TCV
Sophie Danielle Angelica Gorno
Nuclear fusion presents a promising clean energy source to mitigate future energy crises, with magnetic confinement fusion well-positioned to provide a baseload scenario to power future reactors. The unmitigated power exhaust of such reactors threatens its ...
EPFL2024Global fluid simulations of plasma turbulence in stellarators
António João Caeiro Heitor Coelho
In order to cope with the decarbonization challenge faced by many countries, fusion is one of the few alternatives to fossil fuels for the production of electricity. Two devices invented in the middle of the previous century have emerged as the most promis ...
EPFL2024Spectroscopic characterisation of TCV divertor towards a detached regime
The challenge of power exhaust of the high heat and particle fluxes foreseen for ITER and the forthcoming nuclear fusion reactors can be mitigated by operating in a detached divertor regime.This regime has been the object of three decades of studies, as it ...
EPFL2023Systematic extraction of a control-oriented model from perturbative experiments and SOLPS-ITER for emission front control in TCV
Systematic extraction of locally valid dynamic models from experiments is necessary for controller design and the validation of high fidelity models. This paper describes the extraction of a dynamic model in the form of a transfer function, giving the dyna ...
2022Power exhaust by core radiation at COMPASS tokamak
Substantial power dissipation in the edge plasma is required for the safe operation of ITER and next-step fusion reactors, otherwise unmitigated heat fluxes at the divertor plasma-facing components (PFCs) would easily exceed their material limits. Traditio ...
2021H-mode scrape-off layer power width in the TCV tokamak
Basil Duval, Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Umar Sheikh, Roberto Maurizio
Obtaining acceptable conditions at the divertor targets of a next-step fusion experiment based on the tokamak concept is expected to be particularly challenging because of the small predicted value of the plasma power exhaust channel width. An increased co ...
IOP PUBLISHING LTD2021Assessment of alternative divertor configurations as an exhaust solution for DEMO
Holger Reimerdes, Roberto Maurizio, Seungkyu Ha, Hartmut Zohm
Plasma exhaust has been identified as a major challenge towards the realisation of magnetic confinement fusion. To mitigate the risk that the single null divertor (SND) with a high radiation fraction in the scrape-of-layer (SOL) adopted for ITER will not e ...
2020Turbulence and flows in the plasma boundary of snowflake magnetic configurations
Paolo Ricci, Louis Nicolas Stenger, Maurizio Giacomin
The power exhaust through the scrape-off layer (SOL) in fusion reactors is expected to be significantly higher than in ITER, thus questioning the extrapolation of the ITER exhaust solution to these devices. The snowflake (SF) magnetic configuration is one ...
2020Cathodoluminescent screen imaging system for seeded blob detection in toroidal plasma experiment
Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Paul Bowen, Marcelo Baquero Ruiz, Carlos Morais, Fabian Manke
We designed and built a diagnostic based on a cathodoluminescent screen for the detection of turbulent plasma structures with high spatial resolution. The screen is coated with a low threshold energy cathodoluminescent powder that emits light when exposed ...
2020Evaluation of feasibility and costs of alternative magnetic divertor configurations for DEMO
The European roadmap to the realisation of fusion energy has identified a number of technological and scientific challenges towards the development of a DEMO reactor. Mission 2 'Heat-exhaust systems' includes the investigation of alternative divertor confi ...
