Available in PDF, EPUB and Kindle. Book excerpt: Although the electric arc is perhaps the oldest field in elec tronics, it is still one of the least well understood. The beautiful and complex phenomena accompanying the conduction of electricity in gases have led to the development of spectroscopy (and thus of atomic structure and quantum theory), discovery of isotopes, of the electron itself, of X-rays and thus to Moseley's discovery of atomic number, to the discovery of electron emission, and thus to modern electronic technology as well as to much of modern physics. The properties of the plasma state of matter, which until relatively recently could be produced only by the passage of electricity through a gas, have helped explain many natural phenomena ranging from lightning, the aurora, and the ionosphere to solar, stellar, and mushroom-cloud physics. Many plasma devices, such as neon signs, sodium and mercury lamps, thyratrons, ignitrons, and mer cury pool rectifiers, have been with us for decades, and more are still being invented. To name but a few recent ones, we have plasma torches, plasma propulsion devices for space flight, and magnetohydrodynamic generators. Solving the problem of contain ing a high -energy plasma would lead to controlled energy generation by nuclear fusion. Plasma physics is thus more vigorous than ever in spite of its venerable old age. Kesaev's book is concerned in its entirety with one of the least satisfactorily understood aspects of the relation of a plasma to the electrodes bounding and maintaining it.

Download or read book Cathodic Arcs written by André Anders and published by Springer Science & Business Media. This book was released on 2009-07-30 with total page 555 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cathodic arcs are among the longest studied yet least understood objects in science. Plasma-generating, tiny spots appear on the cathode; they are highly dynamic and hard to control. With an approach emphasizing the fractal character of cathode spots, strongly fluctuating plasma properties are described such as the presence of multiply charged ions that move with supersonic velocity. Richly illustrated, the book also deals with practical issues, such as arc source construction, macroparticle removal, and the synthesis of dense, well adherent coatings. The book spans a bridge from plasma physics to coatings technology based on energetic condensation, appealing to scientists, practitioners and graduate students alike.

Available in PDF, EPUB and Kindle. Book excerpt: An experimental and analytical study is made of the emission mechanisms of the mercury arc and it is concluded that the cathode spot temperatures are too low to operate predominately by thermionic emission. Various physical processes to reduce work function are discussed, and shown to be probably not significant. An emission model involving ion microfield emission is proposed and shown to be feasable. The related problem of retrograde arc motion is studied and a model involving plasma growth into large magnetic field regions is proposed. The retrograde arc speed is measured as a function of magnetic field and arc current. The variation of spot size with arc current, magnetic field, and vapor pressure is measured and is compared with a theoretical model based upon low pressure energy balance considerations. Spectrographic measurements show the absence of continuum radiation from the Mo notch cathode and the absence of Mo spectral lines. This suggests that the refractory cathode spot operates at low pressures with little electrode evaporation for the conditions studied. The increase of arc votage with magnetic field was measured and was interpreted as being predominately due to the cathode sheath. (Author).

Download or read book Plasma and Spot Phenomena in Electrical Arcs written by Isak Beilis and published by Springer Nature. This book was released on 2020-09-05 with total page 1137 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to a thorough investigation of the physics and applications of the vacuum arc – a highly-ionized metallic plasma source used in a number of applications – with emphasis on cathode spot phenomena and plasma formation. The goal is to understand the origins and behavior of the various complex and sometimes mysterious phenomena involved in arc formation, such as cathode spots, electrode vaporization, and near-electrode plasma formation. The book takes the reader from a model of dense cathode plasma based on charge-exchange ion-atom collisions through a kinetic approach to cathode vaporization and on to metal thermophysical properties of cathodes. This picture is further enhanced by an in-depth study of cathode jets and plasma acceleration, the effects of magnetic fields on cathode spot behavior, and electrical characteristics of arcs and cathode spot dynamics. The book also describes applications to space propulsion, thin film deposition, laser plasma generation, and magnetohydrodynamics, making this comprehensive and up-to-date volume a valuable resource for researchers in academia and industry.

Available in PDF, EPUB and Kindle. Book excerpt: On first acquaintance the electric arc discharge appears to be both visually attractive and a relatively simple phenomena to understand. To those of us engaged in prolonged study of this discharge, it remains a constantly exciting phenomena but we become only too aware of its complex nature and the difficulties in interpreting its bulk properties. This is particu larly true when the arc exists in a practical device and is subjected therefore to extreme conditions. In recent years the possibilities for the beginning of a fuller understanding of the complexities of the arc has arisen out of the excellent research and development work of scientists and engineers throughout the world. Much of this work has been stimulated not only by the need for the development of practical devices but also by the interest in thermonuclear fusion, mag netohydrodynamic generation and space exploration. In much of this work, the arc discharge has been a common feature as a source of study of high temperature plasma. As a result of this increased interest in the arc, the expert and would-be expert is now faced with the problem of assessing extensive newly published information on arc properties. Thus there is the need for texts which present to the engineer and researcher a review and summary of the present situation. This book is a valuable contribution to this task.

Available in PDF, EPUB and Kindle. Book excerpt: Cathode emission and retrograde motion phenomena were studied for the low pressure anchored mercury arc. Results were obtained from optical measurements of the arc spot size, its optical radiation properties, and its motion about a mercury-wetted anchor in the presence of a strong magnetic field. The shape and spectral emission of the arc column were also examined. Theories are proposed to account for the retrograde motion. A heat balance model of the arc spot is suggested to account for some of the experimental observations, and a modified thermionic emission process is proposed to account for the observed emission current density.
