Predictive power-sharing scaling law in double-null L-mode plasmas

Paolo Ricci, Christian Gabriel Theiler, Louis Nicolas Stenger, Olivier Claude Martin Février, Garance Hélène Salomé Durr-Legoupil-Nicoud

The physical mechanisms regulating the power sharing at the outer targets of L-mode double-null (DN) configurations are investigated using nonlinear, flux-driven, three-dimensional two-fluid simulations. Scans of parameters that regulate the turbulent leve ...

Effect of triangularity on plasma turbulence and the SOL-width scaling in L-mode diverted tokamak configurations

Paolo Ricci, Louis Nicolas Stenger, Maurizio Giacomin, Davide Mancini

The effect of triangularity on tokamak boundary plasma turbulence is investigated using global, flux-driven, three-dimensional, two-fluid simulations. The simulations show that negative triangularity (NT) stabilizes boundary plasma turbulence, and linear i ...

Development of advanced linearized gyrokinetic collision operators using a moment approach

Paolo Ricci, Baptiste Jimmy Frei, Antoine Cyril David Hoffmann, Rogério Manuel Cabete De Jesus Jorge, Louis Nicolas Stenger, Justin Richard Ball

The derivation and numerical implementation of a linearized version of the gyrokinetic (GK) Coulomb collision operator (Jorge et al., J. Plasma Phys., vol. 85, 2019, 905850604) and of the widely used linearized GK Sugama collision operator (Sugama et al., ...

Turbulence and flows in the plasma boundary of snowflake magnetic configurations

Paolo Ricci, Louis Nicolas Stenger, Maurizio Giacomin

Results of 3D, flux-driven, global, two-fluid turbulence simulations are presented for the first time in snowflake (SF) configurations, including the ideal SF, SF plus and SF minus configurations. The analysis is focused on the distribution of the heat flu ...
