Model-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 ...

To the Optimization of Quench Performance for a Large REBCO Cable-in-Conduit Conductor

Davide Uglietti

REBCO cable-in-conduit conductors at the level of tens of kiloamperes are being developed for application in fusion magnets. One important aspect to study is their performance in the case of a quench event. A conductor should survive from such an event wit ...

Negative ion characterization in a helicon plasma source for fusion neutral beams by cavity ring-down spectroscopy and Langmuir probe laser photodetachment

Ivo Furno, Alan Howling, Philippe Frédérique Bruno Guittienne, Rémy Jacquier, Riccardo Agnello, Gennady Plyushchev

Negative ions are characterized in the helicon plasma source resonant antenna ion device (RAID) at the Swiss plasma center by means of cavity ring-down spectroscopy (CRDS) and Langmuir probe (LP)-assisted laser photodetachment. A high density and axially h ...

Investigating Scrape-Off Layer transport in alternative divertor geometries on the TCV tokamak

Roberto Maurizio

Thermonuclear fusion is a potentially clean and limitless energy source that can substantially change the current global electricity generation mix, which is highly dependent on limited fossil fuels. This thesis contributes to the development of fusion en ...

Inter-Layer Joint of Nb3Sn React&Wind Cables for Fusion Magnets

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov, Vincenzo D'Auria

The Swiss Plasma Center (SPC) has developed a layout of Toroidal Field (TF) coil for EUROfusion DEMO tokamak, based on the reference tokamak baseline of 2015. Each TF coil winding pack is wound with graded Nb3Sn conductors and consists of 12 single layers, ...

Turbulence 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 ...

Design Study of a 50-kA React-and-Wind Bi-2212 Cable for Fusion Magnet

Davide Uglietti

In the last few years, the current density of Bi-2212 wires has been greatly improved by filament densify technologies. One further step toward applications in fusion magnets is to design a high current cable, which must overcome the drawbacks of Bi-2212 w ...

Studying the effect of non-adiabatic passing electron dynamics on microturbulence self-interaction in fusion plasmas using gyrokinetic simulations

Ajay Chandrarajan Jayalekshmi

Microturbulence driven by plasma instabilities is in most cases the dominant cause of heat and particle loss from the core of magnetic confinement fusion devices and therefore presents a major challenge in achieving burning plasma conditions. The role of p ...

Assessment 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 ...

Advance in the conceptual design of the European DEMO magnet system

Pierluigi Bruzzone, Kamil Sedlák, Davide Uglietti, Boris Stepanov, Rainer Wesche, Roberto Guarino, Mithlesh Kumar, Vincenzo D'Auria, Ortensia Dicuonzo, Chiara Frittitta, Elena Gaio, Alberto Ferro

The European DEMO, i.e. the demonstration fusion power plant designed in the framework of the Roadmap to Fusion Electricity by the EUROfusion Consortium, is approaching the end of the pre-conceptual design phase, to be accomplished with a Gate Review in 20 ...
