Turbulence in the scrape-off layer of double-null tokamak configurations

Understanding the turbulent dynamics in the outermost region of the tokamak is essential to predict and control the heat and particle loads to the vessel wall, a crucial problem for the entire fusion program. In this thesis, the problem is approached via t ...

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 ...

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

Paolo Ricci, Paola Paruta, Fabio Riva, Christoph Wersal, Baptiste Jimmy Frei, 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 ...

A methodology for the rigorous verification of Particle-in-Cell simulations

Paolo Ricci, Fabio Riva, Carrie Fiona Beadle

A methodology to perform a rigorous verification of Particle-in-Cell (PIC) simulations is presented, both for assessing the correct implementation of the model equations (code verification), and evaluating the numerical uncertainty affecting the simulation ...
