Scrape-Off Layer physics in limited plasmas in TCV

Controlled nuclear fusion is the most promising candidate for being an inexhaustible, clean and intrinsically safe energy source. In the tokamak fusion reactor concept, a high temperature plasma is confined by magnetic fields. Turbulence diffuses the confi ...

Plasma breakdown and current formation in single core and doublet configurations on TCV

Joyeeta Sinha

This thesis presents an experimental investigation of the plasma formation in the TCV tokamak. The primary goal of this work was to program a reliable and smooth plasma formation at several positions within the TCV vessel and then use the gained understand ...

Saturated ideak kink/peeling formations described as three-dimensional magnetohydrodynamic tokamak equilibrium states

Wilfred Anthony Cooper, Basil Duval, Olivier Sauter, Trach-Minh Tran, Holger Reimerdes, Laurie Porte, Jonathan Graves, David Pfefferlé, Daniele Brunetti, Andreas Kleiner, Jonathan Marc Philippe Faustin, Madhusudan Raghunathan, Hamish William Patten

Free boundary magnetohydrodynamic equilibrium states with spontaneous three dimensional deformations of the plasma-vacuum interface are computed for the first time. The structures obtained have the appearance of saturated ideal external kink/peeling modes. ...

A model for the evaluation of the electric field associated with the lightning-triggering rocket wire and its corona

Farhad Rachidi-Haeri, Marcos Rubinstein, Aleksandr Smorgonskii

In this paper, we analyze the electric field at ground level during the first stage of triggered lightning experiments, i.e., during the rocket ascent and prior to the lightning initiation. At distances of some tens of meters from the triggering wire, the ...

Superdiffusive transport in laboratory and astrophysical plasmas

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

In the last few years it has been demonstrated, both by data analysis and by numerical simulations, that the transport of energetic particles in the presence of magnetic turbulence can be superdiffusive rather than normal diffusive (Gaussian). The term ‘su ...

Plasma turbulence, suprathermal ion dynamics and code validation on the basic plasma physics device TORPEX

Ambrogio Fasoli, Ivo Furno, Mario Ludovico Podesta, Francesca Maria Poli, Benoît Labit, Alexandre Dominique Bovet, Joaquim Loizu Cisquella, Gennady Plyushchev, Davoud Iraji, Paolo Ricci, Christian Gabriel Theiler, Kyle Gustafson, Fabio Avino

The TORPEX basic plasma physics device at the Center for Plasma Physics Research (CRPP) in Lausanne, Switzerland is described. In TORPEX, simple magnetized toroidal configurations, a paradigm for the tokamak scrape-off layer (SOL), as well as more complex ...
