Observer-based real-time control for the poloidal beta of the plasma using diamagnetic measurements in tokamak fusion reactors

Stefano Coda, Jean-Marc Moret, Federico Alberto Alfredo Felici, James Paley, Loïc Curchod

The constant technological advances and progresses in tokamak research constantly show up new control challenges. In this context, the control of the poloidal beta has arisen as a relevant issue. In this paper a real-time observer based on the real-time an ...

Understanding and taming plasma blobs in toroidal magnetized plasmas

Ivo Furno

Intermittent blobs, which propagate across a confining magnetic fields, are universally observed in natural and laboratory plasmas. In fusion plasmas, cross-field transport of particles and energy are associated, at least in part, with the propagation of b ...

Recent JET Experiments on Alfvén Eigenmodes with Intermediate Toroidal Mode Numbers: Measurements and Modelling with the TAEFL code

Ambrogio Fasoli, Duccio Testa, Patrick Blanchard, Theodoros Panis

This paper reports the results of recent experiments performed on the JET tokamak on Alfven eigenmodes (AEs) with toroidal mode number (n) in the range n=3—15. The stability properties of these medium-n AEs are investigated experimentally using a new set o ...

Blob current structures in TORPEX plasmas: experimental measurements and numerical simulations

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Christian Gabriel Theiler, Nicola Vianello, Davoud Iraji, Diane Virginie Marie Lançon

In the simple magnetized torus TORPEX, field-aligned blobs originate from ideal interchange waves and propagate radially outward due to del B and curvature induced drifts. Time-resolved two-dimensional measurements of the field-aligned current density J(pa ...

Macroscopic Stability of High Beta MAST plasmas

Jonathan Graves, Wilfred Anthony Cooper

The high-beta capability of the spherical tokamak, coupled with a suite of world-leading diagnostics on MAST, has facilitated significant improvements in the understanding of performance-limiting core instabilities in high performance plasmas. For instance ...

Magnetic energy flows during the current quench and termination of disruptions with runaway current plateau formation in JET and implications for ITER

James Paley

The magnetic energy balance and magnetic energy flows for plasma disruptions in which runaway plateau plasmas are formed and terminated at JET has been analysed and compared with that of runaway-free disruptions. The analysis shows that the energy loss pro ...

Self-Consistent ICRH Distribution Functions and Equilibria in Magnetically Confined Plasmas

Martin Jucker

The deployment of high power radio frequency waves in the ion cyclotron range (ICRF) constitutes an important operational facility in many plasma devices, including ITER. Any charged particle describes a helical motion around a given magnetic field line, t ...

Experimental demonstration of an up-down asymmetry effect on intrinsic rotation in the TCV tokamak

Olivier Sauter, Basil Duval, Alexander Karpushov, Yann Camenen, Alessandro Bortolon, Lucia Isabel Federspiel, Francesco Piras

A new mechanism has recently been proposed that generates a radial flux of parallel momentum in toroidal plasmas. Namely, by considering up-down asymmetric flux surfaces, the symmetry following the magnetic field can be broken and an additional contributio ...

A 3D approach to equilibrium, stability and transport studies in RFX-mod improved regimes

Wilfred Anthony Cooper, Nicola Vianello, Zheng Wang, Elena Gaio, Alberto Ferro

The full three-dimensional (3D) approach is now becoming an important issue for all magnetic confinement configurations. It is a necessary condition for the stellarator but also the tokamak and the reversed field pinch (RFP) now cannot be completely descri ...
