Nonlinear Gyrokinetic Coulomb Collision Operator

Paolo Ricci, Rogério Manuel Cabete De Jesus Jorge, Baptiste Jimmy Frei

A gyrokinetic Coulomb collision operator is derived, which is particularly useful to describe the plasma dynamics at the periphery region of magnetic confinement fusion devices. The derived operator is able to describe collisions occurring in distribution ...

A Gyrokinetic Model for the Tokamak Periphery

Paolo Ricci, Rogério Manuel Cabete De Jesus Jorge, Baptiste Jimmy Frei, Antoine Baillod

Despite significant developments over the last decades, an analytical model which adequately describes plasma dynamics in the tokamak periphery region extending from the edge region to the far scrape-off layer is still missing. In this work, we present a n ...

Theory of the Drift-Wave Instability at Arbitrary Collisionality

Paolo Ricci, Rogério Manuel Cabete De Jesus Jorge

A numerically efficient framework that takes into account the effect of the Coulomb collision operator at arbitrary collisionalities is introduced. Such a model is based on the expansion of the distribution function on a Hermite-Laguerre polynomial basis t ...

An analytical model for scrape-off layer plasma dynamics at arbitrary collisionality

Paolo Ricci, Rogério Manuel Cabete De Jesus Jorge

The lack of an appropriate model to describe the plasma dynamics in the tokamak scrapeoff layer (SOL) has undermined our ability to reliably predict the heat flux to the vessel wall of future fusion devices, one of the most important issues on the way to f ...

A drift-kinetic analytical model for scrape-off layer plasma dynamics at arbitrary collisionality

Paolo Ricci, Rogério Manuel Cabete De Jesus Jorge

A drift-kinetic model to describe the plasma dynamics in the scrape-off layer region of tokamak devices at arbitrary collisionality is derived. Our formulation is based on a gyroaveraged Lagrangian description of the charged particle motion, and the corres ...

Impact of neutral atoms on plasma turbulence in the tokamak edge region

Paolo Ricci, Paola Paruta, Federico David Halpern, Fabio Riva, Christoph Wersal, Rogério Manuel Cabete De Jesus Jorge

A novel first-principles self-consistent model that couples plasma and neutral atom physics suitable for the simulation of turbulent plasma behaviour in the tokamak edge region has been developed [1] and implemented in the GBS code [2]. While the plasma is ...

Parallelization on a Hybrid Architecture of GBS, a Simulation Code for Plasma Turbulence at the Edge of Fusion Devices

Paolo Ricci, Paola Paruta, Trach-Minh Tran, Federico David Halpern, Fabio Riva, Christoph Wersal, Rogério Manuel Cabete De Jesus Jorge, Patrick Emonts

We present recent developments of GBS, a simulation code used to evolve plasma turbulence in the edge of fusion devices. GBS solves a set of 3D fluid equations, the Poisson and the Ampere equation, and a kinetic equation for the neutral atoms. Investigatio ...

Progress in simulating SOL plasma turbulence\\with the GBS code

Paolo Ricci, Paola Paruta, Federico David Halpern, Fabio Riva, Christoph Wersal, Rogério Manuel Cabete De Jesus Jorge

The GBS code has been developed in the last few years to simulate plasma dynamics in tokamak SOL conditions. GBS advances the drift-reduced Braginskii equations, solving at the same time the neutral atoms kinetic equation by the method of characteristics. ...

Plasma turbulence in the scrape-off layer of the ISTTOK tokamak

Paolo Ricci, Federico David Halpern, Rogério Manuel Cabete De Jesus Jorge

The properties of plasma turbulence in a poloidally limited scrape-off layer (SOL) are addressed, with focus on ISTTOK, a large aspect ratio tokamak with a circular cross section. Theoretical investigations based on the drift-reduced Braginskii equations a ...
