Nonclassical Transport and Particle-Field Coupling: from Laboratory Plasmas to the Solar Wind

Ambrogio Fasoli, Ivo Furno, Alexandre Dominique Bovet, Paolo Ricci, Kyle Gustafson

Understanding transport of thermal and suprathermal particles is a fundamental issue in laboratory, solar-terrestrial, and astrophysical plasmas. For laboratory fusion experiments, confinement of particles and energy is essential for sustaining the plasma ...

Tokamak coordinate conventions: COCOS

Olivier Sauter

Dealing with electromagnetic fields, in particular current and related magnetic fields, yields "natural" physical vector relations in 3-D. However, when it comes to choosing local coordinate systems, the "usual" right-handed systems are not necessarily the ...

Turbulent regimes in the tokamak scrape-off layer

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

We identify the turbulent regimes in the tokamak scrape-off layer as a function of plasma resistivity, electron to ion mass ratio, safety factor, and magnetic shear. We find that two main instabilities drive turbulence in the SOL: Drift Waves, with their r ...

Edge Localized Mode Control in TCV

Jonathan Rossel

The Tokamak concept, based on magnetic confinement of a hydrogen plasma, is one of today's most promising paths to energy production by nuclear fusion. The experimental scenarios leading to the largest fusion rate are based on a high confinement plasma reg ...

Measurements of interactions between waves and energetic ions in basic plasma experiments

Ambrogio Fasoli, Ivo Furno, Alexandre Dominique Bovet, Paolo Ricci, Kyle Gustafson, Yi Zhang

To measure the transport of fast ions by various types of waves, complementary experiments are conducted in linear and toroidal magnetic fields in the large plasma device and the toroidal plasma experiment. Lithium sources that are immersed in the plasma p ...

Prototyping Conventionally Wound High-Frequency Magnetic Sensors for ITER

René Chavan, Jonathan Bryan Lister, Jean-Marc Moret, Duccio Testa, Francisco Sanchez, Matthieu Toussaint

The high-frequency (HF) magnetic sensors for ITER are currently based on a conventional, Mirnov-type, pick-up coil, with an effective area in the range 0.03
