On recent results in the modelling of neoclassical-tearing-mode stabilization via electron cyclotron current drive and their impact on the design of the upper EC launcher for ITER

Olivier Sauter, Timothy Goodman, Hartmut Zohm, Emanuele Poli

Electron cyclotron wave beams injected from a launcher placed in the upper part of the vessel will be used in ITER to control MHD instabilities, in particular neoclassical tearing modes (NTMs). Simplified NTM stabilization criteria have been used in the pa ...

The new TORPEX in-vessel toroidal conductor for the generation of a poloidal magnetic field

Ambrogio Fasoli, Ivo Furno, Fabio Avino

TORoidal Plasma EXperiment (TORPEX) is a Simple Magnetized Torus featuring open helical magnetic field lines obtained from the superposition of a small vertical component on the main toroidal field. This work introduces the experimental setup developed to ...

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 ...

Aspect ratio effects on limited scrape-off layer plasma turbulence

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

The drift-reduced Braginskii model describing turbulence in the tokamak scrape-off layer is written for a general magnetic configuration with a limiter. The equilibrium is then specified for a circular concentric magnetic geometry retaining aspect ratio ef ...

Power exhaust in the snowflake divertor for L- and H-mode TCV tokamak plasmas

Basil Duval, Stefano Coda, Holger Reimerdes, Benoît Labit, Wouter Vijvers

The snowflake (SF) divertor is a plasma configuration that may enable tokamak operation at high performance and lower peak heat loads on the plasma-facing components than a standard single-null divertor. This paper reports on the results of experiments per ...

Ideal saturated MHD helical structures in axisymmetric hybrid plasmas

Jonathan Graves, Wilfred Anthony Cooper, Daniele Brunetti

Kinked saturated m = 1 helical structures are frequently observed in tokamak hybrid plasmas and in reversed field pinches (RFP). These modes occur when an extremum in the safety factor is close to, but necessarily resonant with, a low order rational (typic ...

Basic investigations of turbulence and interactions with plasma and suprathermal ions in the TORPEX device with open and closed field lines

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Christian Gabriel Theiler, Joaquim Loizu Cisquella, Fabio Avino, Kyle Gustafson, Alexandre Dominique Bovet

TORPEX is a flexible device dedicated to investigating basic plasma physics phenomena of importance for fusion. It can feature a simple magnetized toroidal (SMT) configuration with a dominant toroidal magnetic field and a small vertical field component, or ...

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 ...

Real-Time multi-EC-actuator MHD control in TCV

Olivier Sauter, Basil Duval, Timothy Goodman, Jonathan Graves, Duccio Testa, Holger Reimerdes, Federico Alberto Alfredo Felici, Doohyun Kim, Donghyun Kim

Real-time control of multiple plasma actuators is a requirement in advanced tokamaks; for example for burn control, plasma current profile control and MHD stabilization - EC wave absorption is ideally suited especially for the latter. For example, on ITER ...
