Blob velocity scaling in diverted tokamaks: A comparison between theory and simulation

Paolo Ricci, Christian Gabriel Theiler, Paola Paruta, Carrie Fiona Beadle

American Institute of Physics (AIP)2019

Simulation of plasma turbulence in the periphery of diverted tokamaks

Paola Paruta

The turbulent plasma dynamics in the periphery of a fusion device plays a key role in determining its overall performance. In fact, the periphery controls the heat load on the vessel walls, the plasma confinement, the level of impurities in the core, the ...

Simulation of plasma turbulence in the periphery of diverted tokamak by using the GBS code

Paolo Ricci, Fabio Riva, Baptiste Jimmy Frei, Christoph Wersal, Paola Paruta, Carrie Fiona Beadle

We report on the implementation of diverted magnetic equilibria in GBS and on first simulations in this geometry. GBS is a simulation code used to evolve plasma turbulence in the tokamak periphery by solving the drift-reduced Braginskii's equations. The mo ...

Scrape-off-layer current loops and floating potential in limited tokamak plasmas

Joaquim Loizu Cisquella, Paolo Ricci, Federico David Halpern, Paola Paruta

We investigate the question of how plasma currents circulate and close in the scrape-off-layer (SOL) of convection-limited tokamak plasmas. A simplified two-fluid model describes how currents must evacuate charge at the sheaths due to cross-field currents ...

Dust grain coagulation modelling: From discrete to continuous

Paola Paruta

In molecular clouds, stars are formed from a mixture of gas, plasma and dust particles. The dynamics of this formation is still actively investigated and a study of dust coagulation can help to shed light on this process. Starting from a pre-existing discr ...
