Argon Plasma Simulations for Educational Purposes at Fontys University of Applied Physics

H. van Halewijn [1],
[1] Fontys University of Applied Physics, The Netherlands

At the Fontys University of Applied Physics (The Netherlands) a plasma etcher has been acquired for educational purposes. The machine operates at low power up to 30 Watt and is driven with a magnetic coil at 13.56 MHz. The use of COMSOL Multiphysics software will be discussed to simulate ... Per saperne di più

Photonic Crystal Fibers for Visible Light Generation

D. Aydin [1], S. J. Cordette [1], C. Brès [1],
[1] EPFL, Lausanne, Vaud, Switzerland

There has been a growing interest in optical parametric amplifiers (OPA) for light generation and amplification in because of the possibility for arbitrary operation wavelength and wideband tenability [1]. PCFs are of particular interest in such nonlinear optics applications because of ... Per saperne di più

A COMSOL-based 2D Self-Consistent Microwave Plasma Model

A. Berthelot [1], A. Bogaerts [1],
[1] PLASMANT Group, University of Antwerp, Belgium

In this paper, we present a 2D axisymmetric self-consistent plasma fluid model for microwave plasmas operating in argon. The model was developed using COMSOL Multiphysics and its Plasma Module. Plasma, flow, heat and electromagnetic equations solved self-consistently. The effect of the ... Per saperne di più

Scattering of mm-Waves by Turbulent Structures in Magnetically Confined Fusion Plasmas

O. Chellaï [1], S. Alberti [1], I. Furno [1], T. Goodman [1], M. Baquero [1]
[1] Centre de Recherches en Physique des Plasmas, Ecole Polytechnique Fédérale de Lausanne, Suisse

In magnetically confined fusion devices, electron cyclotron resonance heating (80-170 GHz) is characterized by a local RF-power deposition at the electron cyclotron resonance [1]. A mm-wave RF Gaussian beam is launched from a dedicated antenna and propagates through the highly turbulent ... Per saperne di più
