Gyrokinetic simulations of plasma turbulence in a Z-pinch using a moment based approach and advanced collision operators
A. C. D. Hoffmann, B. J. Frei, P. Ricci
The first nonlinear gyrokinetic simulations obtained using a moment approach based on the Hermite-Laguerre decomposition of the distribution function are presented, implementing ad…
Turbulent transport regimes in the tokamak boundary and operational limits
M. Giacomin, P. Ricci
Two-fluid, three-dimensional, flux-driven, global, electromagnetic turbulence simulations carried out by using the GBS code are used to identify the main parameters controlling tur…
First-principles density limit scaling in tokamaks based on edge turbulent transport and implications for ITER
M. Giacomin, A. Pau, P. Ricci +2

On a Frequency-Stabilized Single Current Inverse Source Formulation
Paolo Ricci, Adrien Merlini, Francesco P. Andriulli
Several strategies are available for solving the inverse source problem in electromagnetics. Among them, many have been focusing in retrieving Love currents by solving, after regul…
Numerical Implementation of the Improved Sugama Collision Operator Using a Moment Approach
B. J. Frei, S. Ernst, P. Ricci
The numerical implementation of the linearized gyrokinetic (GK) and drift-kinetic (DK) improved Sugama (IS) collision operators, recently introduced by Sugama et al. [Phys. Plasmas…
