Simulation of bootstrap current in 2D and 3D ideal magnetic fields in Tokamaks

Olivier Sauter, Jonathan Graves, Wilfred Anthony Cooper, Madhusudan Raghunathan, Michael Pedro

We aim to simulate the bootstrap current for a MAST-like spherical tokamak using two approaches for magnetic equilibria including externally caused 3D effects such as Resonant Magnetic Perturbations (RMPs), the effect of toroidal ripple, and intrinsic 3D e ...

High density experiments in TCV ohmically heated and L-mode plasmas

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Benoît Labit, Laurie Porte, Alexander Karpushov, Antoine Pochelon, Roland Behn

Recent experiments have been performed on the Tokamak a configuration variable (TCV) to investigate the confinement properties of high density plasmas and the mechanism behind the density limit. In a limiter configuration with plasma elongation kappa = 1.3 ...

Achieving and sustaining advanced scenarios in ITER modelled by CRONOS and DINA-CH

Jonathan Bryan Lister, Javier García Hernández, Karim Besseghir

The heating and current drive characteristics for accessing advanced scenarios in ITER, close to those obtained in present-day experiments, are analysed together with the plasma performance using the prescribed-boundary CRONOS suites of codes. For the hybr ...

Global electromagnetic simulations of tokamak scrape-off layer turbulence

Paolo Ricci, Joaquim Loizu Cisquella, Sébastien Jolliet, Federico David Halpern, Annamaria Mosetto

We discuss recent studies addressing the properties of tokamak SOL turbulence using a global, electromagnetic, fluid drift-reduced Braginskii model. Non-linear simulations are carried out using the Global Braginskii Solver (GBS) code [1], which is capable ...

Three-dimensional equilibria and transport in RFX-mod: A description using stellarator tools

Wilfred Anthony Cooper

RFX-mod self-organized single helical axis (SHAx) states provide a unique opportunity to advance 3D fusion physics and establish a common knowledge basis in a parameter region not covered by stellarators and tokamaks. The VMEC code has been adapted to the ...

Ideal MHD spectrum calculations for the ARIES-CS configuration

Wilfred Anthony Cooper

Ideal MHD stability calculations for the ARIES compact stellarator (ARIES-CS) reactor design (Najmabadi et al 2008 Fusion Sci. Technol. 54 655) show a spectrum of instabilities. The ARIES design considered is a three field-period stellarator with engineeri ...

Global Nonlinear Electromagnetic Simulations of Tokamak Turbulence

Laurent Villard, Stephan Brunner, Trach-Minh Tran, Alberto Bottino, Sébastien Jolliet, Ben McMillan, Thibaut Vernay

The particle-in-cell code ORB5 is a global gyrokinetic turbulence simulation code in tokamak geometry. It has been developed at CRPP, Lausanne, Switzerland, with major contributions from IPP, Garching, Germany, and IPP, Greifswald, Germany, under a long-st ...

Transport and turbulence reduction with negative triangularity : Correlation ECE measurements in TCV

Olivier Sauter, Basil Duval, Stefano Coda, Timothy Goodman, Laurent Villard, Jean-Marc Moret, Stephan Brunner, Benoît Labit, Laurie Porte, Alexander Karpushov, Antoine Pochelon, Yann Camenen, Roland Behn, Alberto Bottino, Sébastien Jolliet, Emiliano Fable, Philippe Marmillod, Ben McMillan, Alessandro Marinoni, Lucia Isabel Federspiel, Andreas Pitzschke, Mikael Rancic

Turbulence and Transport Reduction with Negative Triangularity : Correlation ECE Measurements in TCV Due to turbulence, core energy transport in fusion devices such as tokamaks generally exceeds collisional transport by at least an order of magnitude. It i ...

Plasma fluctuation studies in the TCV tokamak

Alessandro Marinoni

One of the most important issues for magnetic-confinement fusion research is the so-called anomalous transport across magnetic field lines, i.e. transport that is in excess of that caused by collisional processes. The need to reduce anomalous transport in ...
