The Science Program of the TCV Tokamak: Exploring Fusion Reactor and Power Plant Concepts

TCV is acquiring a new 1 MW neutral beam and 2 MW additional third-harmonic electron cyclotron resonance heating (ECRH) to expand its operational range. Its existing shaping and ECRH launching versatility was amply exploited in an eclectic 2013 campaign. A ...

Electromagnetic turbulence simulations of the tokamak scrape-off layer

Federico David Halpern

We present the newest version of the Global Braginskii Solver (GBS), which addresses tokamak boundary turbulence. GBS now employs a 3D cartesian communicator and a parallel multigrid Poisson/Ampere solver, achieving excellent parallel scalability, and it i ...

A flexible numerical scheme for simulating plasma turbulence in the tokamak scrape-off layer

Paolo Ricci, Paola Paruta, Federico David Halpern, Fabio Riva

Simulating the most external plasma region of a tokamak, the scrape-off layer (SOL), is of crucial importance in the way toward a fusion reactor as heat load on the vessel wall, impurity generation, overall plasma confinement, all depend on the plasma dyna ...

Plasma turbulence, suprathermal ion dynamics and code validation on the basic plasma physics device TORPEX

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Benoît Labit, Christian Gabriel Theiler, Joaquim Loizu Cisquella, Mario Ludovico Podesta, Fabio Avino, Francesca Maria Poli, Gennady Plyushchev, Kyle Gustafson, Alexandre Dominique Bovet, Davoud Iraji

The TORPEX basic plasma physics device at the Center for Plasma Physics Research (CRPP) in Lausanne, Switzerland is described. In TORPEX, simple magnetized toroidal configurations, a paradigm for the tokamak scrape-off layer (SOL), as well as more complex ...

Experiments on magneto-hydrodynamics instabilities with ECH/ECCD in FTU using a minimal real-time control system

Cristian Galperti

Experiments on real time control of magneto-hydrodynamic (MHD) instabilities using injection of electron cyclotron waves (ECW) are being performed with a control system based on only three real time key items: an equilibrium estimator based on a statistica ...

Novel aspects of plasma control in ITER

Olivier Sauter, Federico Alberto Alfredo Felici, Jonathan Bryan Lister, Sun Hee Kim

ITER plasma control design solutions and performance requirements are strongly driven by its nuclear mission, aggressive commissioning constraints, and limited number of operational discharges. In addition, high plasma energy content, heat fluxes, neutron ...

Simulation of the scrape-off layer region of tokamak devices

Paolo Ricci

Understanding the key processes occurring in the tokamak scrape-off layer (SOL) is becoming of the outmost importance while we enter the ITER era and we move towards the conception of future fusion reactors. By controlling the heat exhaust, by playing an i ...

Effects of plasma shaping on tokamak scrape-off layer turbulence

Paolo Ricci, Emmanuel Lanti, Sébastien Jolliet, Federico David Halpern, Fabio Riva

The understanding of the plasma dynamics in the scrape-off layer (SOL) of tokamaks is of crucial importance as we approach the ITER era. In this region, particles and heat coming from the core, through turbulent transport, flow along the magnetic field lin ...

Effects of central electron cyclotron power on plasma rotation and on triggerless onset of NTMs in the TCV tokamak

Olivier Sauter, Basil Duval, Duccio Testa, Holger Reimerdes, Alexander Karpushov, Doohyun Kim, Dávid Wágner, Lucia Isabel Federspiel, Jonathan Rossel, Donghyun Kim

Experiments on the TCV tokamak show that high power central electron cyclotron heating (ECH) and current drive (ECCD) produce significant direct modification of the plasma rotation profile, as well as the effect on the equilibrium current density. These ef ...

X-point Position Dependence of Edge Intrinsic Toroidal Rotation on TCV

Olivier Sauter, Basil Duval, Holger Reimerdes, Benoît Labit, Alexander Karpushov, Wouter Vijvers

Recent theoretical work predicts intrinsic toroidal rotation in the tokamak edge to depend strongly on the normalized major radial position of the X-point. With this motivation, we conducted a series of Ohmic L-mode shots on the Tokamak a Configuration Var ...
