Long plasma duration operation analyses with an international multi-machine (tokamaks and stellarators) database
Combined high-fusion performance and long-pulse operation is one of the key integration challenges for fusion energy development in magnetic devices. Addressing these challenges requires an integrated vision of physics and engineering aspects with the purp ...
Bristol2024Global 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 ...
EPFL2024ICRH assisted breakdown study on JET
Benoît Labit, Haomin Sun, Thomas Binderup Jensen
Ion cyclotron (IC) wave assisted breakdown has the potential to increase the robustness of plasma initiation during the ITER pre-fusion operation phase. Studies were performed at JET at ITER relevant loop electric field, E-loop ? 0.33 Vm(-1), and a range o ...
IOP Publishing Ltd2023Feasibility of the EDICAM camera for runaway electron detection in JT-60SA disruptions
The visible camera system EDICAM (Event Detection Intelligent Camera), recently installed on JT-60SA, is simulated to assess whether it can be used for measuring synchrotron radiation from relativistic runaway electrons. In this simulation, the SOFT synthe ...
ELSEVIER SCIENCE SA2023EAST discharge prediction without integrating simulation results
Alessandro Pau, Xiaojuan Liu, Chenguang Wan
In this work, a purely data-driven discharge prediction model was developed and tested without integrating any data or results from simulations. The model was developed based on the experimental data from the Experimental Advanced Superconducting Tokamak ( ...
2022The SparSpec algorithm and the application to the detection of spatial periodicities in tokamaks: from a 1D to a 2D analysis
A well-known, previously only 1D, algorithm using the Sparse Representation of Signals and an iterative Block Coordinate Descent method (the SparSpec-1D algorithm) has been further developed and tested in a 2D spatial domain to obtain the toroidal and polo ...
IOP Publishing Ltd2022Physics of runaway electrons with shattered pellet injection at JET
Cristian Sommariva, Javier García Hernández, Gergely Papp
Runaway electrons (REs) created during tokamak disruptions pose a threat to the reliable operation of future larger machines. Experiments using shattered pellet injection (SPI) have been carried out at the JET tokamak to investigate ways to prevent their g ...
IOP Publishing Ltd2022Model-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 ...
EPFL2021Physics 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 PHYSICS2021Drift-related transport and plasma-neutral interaction in the TCV divertor
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 ...
