Efficient generation of energetic ions in multi-ion plasmas by radio-frequency heating

Henri Weisen, Jonathan Marc Philippe Faustin, Yu Lin

We describe a new technique for the efficient generation of high-energy ions with electromagnetic ion cyclotron waves in multi-ion plasmas. The discussed three-ion scenarios are especially suited for strong wave absorption by a very low number of resonant ...

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 ...

A flexible numerical scheme for simulating plasma turbulence in the tokamak scrape off layer

Paolo Ricci, Paola Paruta, Fabio Riva, Christoph Wersal

Simulating the most external plasma region of a tokamak, the scrape-off layer (SOL), is of crucial importance in the way towards a fusion reactor as heat load on the vessel wall, impurity generation, and overall plasma confinement, all depend on the plasma ...

Modeling of neoclassical tearing mode stabilization by electron cyclotron heating and current drive in tokamak plasmas

Olivier Sauter, Federico Alberto Alfredo Felici, Kyungjin Kim, Hartmut Zohm, Emanuele Poli

An integrated numerical system is established to model time-dependent behavior of the neoclassical tearing mode (NTM) in a tokamak which solves the modified Rutherford equation (MRE) by coupling with plasma transport, equilibrium, heating and current drive ...

Interaction of neutral atoms and plasma turbulence in the tokamak edge region

Paolo Ricci, Paola Paruta, 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 and implemented in the GBS code. While the plasma is modelle ...

Wireless Channel Characterization in Burning Buildings Over 100-1000 MHz

Andrew Charles Mallory Austin

A 3-D implementation of the finite-difference time-domain (FDTD) method is used to model 100-1000-MHz radio wave propagation in a generalized office building. Fire within this building is modeled as a cold plasma medium. The presence of fire is found to de ...

Numerical approach to the parallel gradient operator in tokamak scrape-off layer turbulence simulations and application to the GBS code

Paolo Ricci, Joaquim Loizu Cisquella, Sébastien Jolliet, Federico David Halpern, Fabio Riva, Annamaria Mosetto

This paper presents two discretisation schemes for the parallel gradient operator used in scrape-off layer plasma turbulence simulations. First, a simple model describing the propagation of electrostatic shear-Alfven waves, and retaining the key elements o ...

Superdiffusive transport in laboratory and astrophysical plasmas

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Kyle Gustafson, Alexandre Dominique Bovet

In the last few years it has been demonstrated, both by data analysis and by numerical simulations, that the transport of energetic particles in the presence of magnetic turbulence can be superdiffusive rather than normal diffusive (Gaussian). The term ‘su ...
