Understanding the turbulent mechanisms setting the density decay length in the tokamak scrape-off layer

Paolo Ricci, Carrie Fiona Beadle

Mechanisms setting the density decay in the scrape-off layer (SOL) at the outer midplane of a tokamak plasma are disentangled using two-fluid numerical simulations in a double-null magnetic configuration and analytical estimates. Typical experimental obser ...

Inter-Layer Joint of Nb3Sn React&Wind Cables for Fusion Magnets

Pierluigi Bruzzone, Kamil Sedlák, Boris Stepanov, Vincenzo D'Auria

The Swiss Plasma Center (SPC) has developed a layout of Toroidal Field (TF) coil for EUROfusion DEMO tokamak, based on the reference tokamak baseline of 2015. Each TF coil winding pack is wound with graded Nb3Sn conductors and consists of 12 single layers, ...

Nonlinear dynamics of energetic-particle driven geodesic acoustic modes in ASDEX Upgrade

Laurent Villard, Emmanuel Lanti, Alberto Bottino, Noé Thomas Elie Ohana, Emanuele Poli

Turbulence in tokamaks generates radially sheared zonal flows. Their oscillatory counterparts, geodesic acoustic modes (GAMs), appear due to the action of the magnetic field curvature. The GAMs can be driven unstable by an anisotropic energetic particle (E ...

Numerical investigation of optimal divertor gas baffle closure on TCV

Stefano Coda, Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Davide Galassi, Mirko Wensing

A first set of divertor gas baffles has recently been installed in the TCV tokamak. In order to explore the physics determining the benefits and limitations of divertor baffling and to guide the design of a possible second generation of baffles, the effect ...
