Global two-fluid simulations of tokamak Scape-Off-Layer turbulence

Paolo Ricci, Sébastien Jolliet, Federico David Halpern, Annamaria Mosetto

We present non-linear self-consistent 3D global fluid simulations of the SOL plasma dynamics using the Global Braginskii Solver (GBS) code. The code solves the drift-reduced Braginkii equations in a collisional plasma, with cold ions. The GBS code, origina ...

Magnetic Field Induced Redistribution of Exciton-Polariton Density on Confined Modes

Benoît Marie Joseph Deveaud, Gaël Nardin, François Morier-Genoud, Barbara Pietka

The influence of magnetic field on confined exciton-polariton modes inside a semiconductor microcavity is discussed. The three-dimensional confinement for exciton-polaritons is achieved by the mesa structures confining the photonic part of polaritons. We o ...

Ideal MHD stability of helically symmetric magnetic islands

Laurent Villard, Andrei Martynov

A new version of the MHD_NX code, that computes the ideal MHD stability of helically symmetric equilibria with arbitrary topology of magnetic surfaces, was applied to the investigation of equilibrium magnetic islands in tokamak-like conditions. Any helical ...

Study of the ITER Stray Magnetic Field Effect on the EU 170-GHz2-MW Coaxial Cavity Gyrotron

Stefano Alberti, Jean-Philippe Hogge, Ioannis Pagonakis, Fengping Li

In this paper, the effect of the ITER stray magnetic field (SMF) on the operation of the European gyrotron has been studied. The SMFs include the magnetic field generated by neighboring gyrotrons, the ITER tokamak, and also the field perturbations caused b ...

First fluctuation measurements in the new confined plasma configuration of the TORPEX device

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Joaquim Loizu Cisquella, Fabio Avino, Annamaria Mosetto, Alexandre Dominique Bovet

The basic plasma physics device TORPEX features some of the main ingredients of the Scrape-Off Layer (SOL) of fusion devices, including gradients of density and magnetic field, as well as magnetic field curvature. A simple magnetized torus configuration (S ...

Electric field control of the skyrmion lattice in Cu2OSeO3

Henrik Moodysson Rønnow, Ivica Zivkovic, Helmuth Berger, Jonathan White, Krunoslav Prsa, Arash Alahgholipour Omrani

Small-angle neutron scattering has been employed to study the influence of applied electric (E-) fields on the skyrmion lattice in the chiral lattice magnetoelectric Cu2OSeO3. Using an experimental geometry with the E-field parallel to the [111] axis, and ...

Combined use of transcranial magnetic stimulation and metal electrode implants: a theoretical assessment of safety considerations

Juan Ramon Mosig, Hossein Rouhani, Laleh Golestanirad, Kamal Shahim

This paper provides a theoretical assessment of the safety considerations encountered in the simultaneous use of transcranial magnetic stimulation (TMS) and neurological interventions involving implanted metallic electrodes, such as electrocorticography. M ...

Fluorescent magnetic bead and cell differentiation/counting using a CMOS SPAD matrix

Edoardo Charbon, Martinus Gijs, Ulrike Lehmann, Caroline Vandevyver, Emile Dupont

We present a monolithic silicon chip comprising a matrix of 84 single photon avalanche diodes (SPADs) to detect and discriminate fluorescent beads or fluorescently labeled single cells in a polydimethyl(-siloxane) (PDMS) cartridge that is positioned on top ...

Global two-fluid simulations of tokamak SOL turbulence

Paolo Ricci, Federico David Halpern, Annamaria Mosetto

We present non-linear self-consistent global simulations of the SOL plasma dynamics using the Global Braginskii Solver (GBS) code. The code solves on the drift-reduced Braginkii equations, with cold ions. Studied originally for the simulation of the Simple ...
