With this presentation, some content has been discussed from several parts as follows: 1. Plasma switches are introduced by their derivation and types, and the operating mechanism of Hydrogen cross field plasma switch is indicated then. 2. The related theories of Hydrogen plasma to ... Read More
The computer simulation with COMSOL Multiphysics has become a widely used technique for the study of various problems in the field of plasma physics. Despite the increasing performance of computers, fully three-dimensional particle simulations still have got extremely high demands on ... Read More
The axial injection torch (AIT) produces high-density plasmas by coupling microwave power to a flowing gas. The plasma is imposed by defining its electron density and temperature whose maximum are given by optical emission spectroscopy diagnostics. Our study of an AIT with COMSOL ... Read More
Neutral Beam Injectors for ITER require development of negative ion sources and beams with carefully reduced beam divergence. In the accelerator this is compensated by the focusing due to the fringe effect of the electric field, while in the drift region, where the beam is propagating ... Read More
2D self-consistent nonequilibrium model of a free-burning arc in argon has been developed. The model is based on the COMSOL Multiphysics® platform and describes in a self-consistent manner the fluid dynamics, the heat transfer, the magneto-electrodynamics, and species conservation. The ...

Electrostatically excited plasma waves can induce a “plasma wind” in the surrounding media or air. The lifted object has a shape of a flying saucer, just for better illustration. A travelling plasma wave propulsion requires a pre-ionized media around the surface and a travelling ... Read More
This work describes a model for plasma formation in the keyhole and above the EBW zone. The parameters of the plasma are closely connected to the characteristics of the thermal action of the electron beam on the welded metal, which allows operational control and study of EBW. The ... Read More
Ar/H2 discharges are frequently used in various industrial applications, such as etching processes, surface treatment, and film deposition. In the discharges, the active species, such as ions and hydrogen atoms, are responsible for surface reactions, which could be considered as the ... Read More
Plasma spraying is one of the prominent technologies for wear, corrosion and high temperature resistant coatings. The coating quality is very important to increase the performance of the components as well as to protect the outer surface of the component from external environment. The ... Read More
Chemical vapor deposition (CVD) is a promising effective method for synthesis of graphene films. CVD graphene film is obtained from hydrocarbon species such as CH4 through complex catalytic chemical reactions on the surface of the catalyst. Therefore, studying the catalytic reaction ... Read More
