Effect of the limiter position on the scrape-off layer width, radial electric field and intrinsic flows

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

The effect of the limiter position on the scrape-off layer (SOL) width, radial electric field and intrinsic flows is investigated via global, three-dimensional turbulence simulations in four different limiter configurations. The limiter position affects th ...

Complete multi-field characterization of the geodesic acoustic mode in the TCV tokamak

Stefano Coda, Laurent Villard, Stephan Brunner, Laurie Porte, Zhouji Huang, Gabriele Merlo, Julien Stanislas Pierre Dominski, Thibaut Vernay, Cornelis Adrianus de Meijere

The geodesic acoustic mode (GAM) is a coherently oscillating zonal flow that may regulate turbulence in toroidal plasmas. Uniquely, the complete poloidal and toroidal structure of the magnetic component of the turbulence-driven GAM has been mapped in the T ...

Basic characterization of TORPEX electrostatic modes in closed field line configurations

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Fabio Avino, Sébastien Jolliet

Electrostatic coherent modes are studied in the TORPEX device [Fasoli et al., Plasma Phys. Controlled Fusion 52, 124020 (2010)], in closed flux surfaces. The accessibility to this magnetic geometry is provided by a current-carrying in-vessel toroidal condu ...

NBI fast ion confinement in the helical core of MAST hybrid-like plasmas

Jonathan Graves, Wilfred Anthony Cooper, David Pfefferlé, Cyril Misev

Energetic ions are found to be transported strongly from the core of MAST hybrid-like plasmas during long-lived mode (LLM) magnetohydrodynamic activity. The resulting impact on the neutral beam ion deposition and concurrent current drive is modelled usin ...

Multi-objective Optimization of a Solar Assisted 1st and 2nd Generation Sugarcane Ethanol Production Plant

François Maréchal, Adriano Viana Ensinas, Alberto Mian, Anna Sophia Wallerand, Gianluca Ambrosetti, Juliana Queiroz Albarelli

Ethanol production sites utilizing sugarcane as feedstock are usually located in regions with high land availability and decent solar radiation. This offers the opportunity to cover parts of the process energy demand with concentrated solar power (CSP) and ...

Relevant impact of irradiance (vs. dose) and evolution of pH and mineral nitrogen compounds during natural water disinfection by photo-Fenton in a solar CPC reactor

César Pulgarin, Juliette Ndounla

The inactivation of total coliforms/E. coli (10(4) CFU/mL) and Salmonella spp. (10(5) CFU/mL) in well water naturally containing dissolved (Fe2+/3+) and solid iron forms (e.g. iron oxides) was carried out by photo Fenton treatment (Fe-2+,Fe-3+/H2O2/hv). In ...

Three-dimensional distortions of the tokamak plasma boundary: boundary displacements in the presence of saturated MHD instabilities

Jonathan Graves, Wilfred Anthony Cooper, Daniele Brunetti

The three-dimensional plasma boundary displacement induced by long-lasting core magnetohydrodynamic (MHD) instabilities has been measured in JET, MAST and NSTX. Only saturated instabilities are considered here since transient rapidly growing modes which de ...

Plasma turbulence studies in TORPEX basic plasma pyhsics device: from concentric flux surfaces to single null X-points

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Fabio Avino, Alexandre Dominique Bovet

TORPEX is a basic plasma physics device where a simple magnetized torus (SMT) is produced by adding a small vertical magnetic field to a main toroidal component, generating helical field lines. The SMT configuration features the main ingredients of a tokam ...

Global gyrokinetic stability of collisionless microtearing modes in large aspect ratio tokamaks

Laurent Villard, Stephan Brunner

Linear full radius gyrokinetic calculations show the existence of unstable microtearing modes (MTMs) in purely collisionless, high temperature, large aspect ratio tokamak plasmas. The present study takes into account fully gyrokinetic highly passing ions a ...
