Generalization of a fast, predictive model for tokamak scenario design in ASTRA and comparison to a RAPTOR model

Early heating tokamak plasmas during the current ramp-up is a common approach to efficiently access advanced tokamak (AT) configurations. We have previously presented an analytical predictive model to aid in the AT scenario design, optimized for a single s ...

The quasi-continuous exhaust regime in JET

Olivier Sauter, Benoît Labit

The quasi-continuous exhaust (QCE) regime is a regime that is naturally type-I ELM-free. It combines the high density at the plasma edge needed for power exhaust with the high normalised energy confinement typical for H-mode operation. In the QCE regime la ...

A control oriented strategy of disruption prediction to avoid the configuration collapse of tokamak reactors

Patrick Blanchard, Ambrogio Fasoli, Olivier Sauter, Henri Weisen, Duccio Testa, Federico Alberto Alfredo Felici, Umar Sheikh, Paulo Giovane Paschoali Pereira Puglia, Eduardo José Lascas Neto, Cristian Sommariva, Davide Galassi, Mike Machielsen, Alessandro Pau, Gino Marceca

The objective of thermonuclear fusion consists of producing electricity from the coalescence of light nuclei in high temperature plasmas. The most promising route to fusion envisages the confinement of such plasmas with magnetic fields, whose most studied ...

Fast dynamic 1D simulation of divertor plasmas with neural PDE surrogates

Yoeri Renier Johannes Poels

Managing divertor plasmas is crucial for operating reactor scale tokamak devices due to heat and particle flux constraints on the divertor target. Simulation is an important tool to understand and control these plasmas, however, for real-time applications ...

Self-consistent gyrokinetic modeling of turbulent and neoclassical tungsten transport in toroidally rotating plasmas

Kyungtak Lim

The effect of toroidal rotation on both turbulent and neoclassical transport of tungsten (W) in tokamaks is investigated using the flux-driven, global, nonlinear 5D gyrokinetic code GYSELA. Nonlinear simulations are carried out with different levels of mom ...

Alfven cascade eigenmodes above the TAE-frequency and localization of Alfven modes in D-He-3 plasmas on JET

Henri Weisen

Various types of Alfven eigenmodes (AEs) have been destabilized by fast ions over a broad frequency range from similar to 80 kHz to similar to 700 kHz in a series of JET experiments in mixed D-He-3 plasmas heated with the three-ion ICRF scenario (2020 Noce ...

Experimental Assessment of the Thermal Strain Distribution in Nb3Sn React & Wind Conductor Prototype for European DEMO

Kamil Sedlák, Chiara Frittitta

In a typical Nb3Sn cable for fusion applications, the knowledge of the strain state of Nb3Sn filaments is important to predict and interpret the conductor performance in operation. Amongst the relevant strain sources, the predominant is the thermal strain ...
