A kinetic neutral atom model for tokamak SOL turbulence simulations

Paolo Ricci, Federico David Halpern, Fabio Riva, Christoph Wersal

The first-principle understanding of the processes in the Scrape-Off-Layer (SOL) of a tokamak is crucial for the developement of a thermonuclear reactor. Since the plasma temperature in the SOL is rather low, the plasma is typically not fully ionized, and ...

The first-principle understanding of the processes in the Scrape-Off-Layer (SOL) of a tokamak is crucial for the developement of a thermonuclear re- actor. Since the plasma temperature in the SOL is rather low, the plasma is typically not fully ionized, an ...

Reduced Electron Model with Accurate Trapping Effects for Non-Linear Ion Accoustic Waves

Stephan Brunner, Luca Delacrétaz

Ion Accoustic Wave (IAW) dynamics are usually simulated assuming an isothermal Boltzmann ﬂuid response of the electrons. It has been shown that results from the Boltzmann model may signiﬁcantly diﬀer from cor- responding ones obtained considering the fully ...

Exact results for thermodynamics of the hydrogen plasma: Low-temperature expansions beyond Saha theory

We study hydrogen in the Saha regime, within the physical picture in terms of a quantum proton-electron plasma. Long ago, Saha showed that, at sufficiently low densities and low temperatures, the system behaves almost as an ideal mixture made with hydrogen ...

Understanding the relations between QSOs and their host galaxies from combined HST imaging and VLT spectroscopy

Frédéric Courbin

host galaxies of six nearby QSOs are studied on the basis of high-resolution HST optical images and spatially resolved VLT slit spectra. The gas ionization and velocity are mapped as a function of the distance to the central QSO. In the majority of the cas ...

Plasma production by low-field side injection of electron cyclotron waves in a simple magnetized torus

Ambrogio Fasoli, Benoît Labit, Mario Ludovico Podesta, Francesca Maria Poli

The mechanisms leading to ionization of neutral gas by means of microwaves in the electron cyclotron range of frequencies in a simple toroidal plasma configuration are investigated in the TORPEX device (Fasoli A et al 2003 Bull. Am. Phys. Soc. 48 119). The ...
