Investigative Studies of Plasma Torch Hazards
American Industrial Hygiene Association Journal, 1968Abstract Potential health hazards from a medium output plasma torch used in a biological laboratory were investigated, and some industrial applications of higher output plasma torches were surveyed. Exposures to intense ultraviolet radiation, noise, and noxious gases and fumes were measured.

With acetone as a catalyst in an argon discharge plasma, it is observed that localized high-density anode spots can be formed at sharp edges in the plasma. By placing the sharp edge on top of a small permanent magnet, the current which is attracted to the spot can locally burn a piece of metal beneath the sharp edge.

Numerical modelling of physical properties and processes in an electric arc stabilized by a water vortex (steam torch) has been summarized in this review paper. One-fluid MHD equations are numerically solved for an axisymmetric thermal plasma flow inside a discharge chamber of the steam plasma torch.

Plasma torch igniter for scramjets
Journal of Propulsion and Power, 1989A small, uncooled plasma torch was developed and used in combination with an injector designed to study ignition and flameholding in hydrogen-fueled supersonic flows. The plasma torch was operated on mixtures of hydrogen and argon with total flows of 10 to 70 scfh.

Ion implantation for plasma torches
Vacuum, 2002Abstract It has been shown before that the erosion of a cathode is related to the condition of its surface, particularly with respect to its composition. The composition of the surface seems to affect different parameters, including the work function of the surface.

Reviews of Physics in Technology, 1971
The design principles and construction are first presented and the important problem of plasma stability and the methods of maintaining stability, over a range of conditions and in different gases, are then considered. The power supplies and the various methods that have been used to initiate the torches are described.

The plasma torch is a poorly understood, little known prodigy among the physical modalities used in medicine. It is unknown to most physicians because it is presently an experimental tool, references in the medical literature are sparse, and it masquerades under several aliases.

This chapter focuses on the theoretical description of the physical processes in the Arc plasma torches with different technological applications. The features of electric Arcs and their models for the study of Arc plasma torches are presented. The need to determine the two-dimensional electromagnetic field, especially in the case of an open free Arc ...

Electrode Phenomena in Plasma Torches
Annals of the New York Academy of Sciences, 1999ABSTRACT: The performance of most plasma generators using electric arcs is determined by the design of the electrodes. While the cathode design is the dominant factor in determining the limitations in torch operating current and power level as well as life between maintenance, the anode design dominates the functional performance for most torches, i.e.

Attenuation of microwaves by plasma torches
ICOPS 2000. IEEE Conference Record - Abstracts. 27th IEEE International Conference on Plasma Science (Cat. No.00CH37087), 2002Summary form only given. An experiment has been conducted in a rectangular waveguide to study the effectiveness of plasma torches on microwave absorption. Three torch modules are mounted on the bottom wall of a rectangular X-band waveguide (1 in./spl times/2 in.), so that the plasma produced by the torch crosses the path of propagation of the microwave
