Book Description
This is an up-to-date review of studies in the physics of pulsed electrical discharges in a vacuum. It gives the reader detailed information on the processes occurring at electrodes and in vacuum gaps and on the mechanisms of discharge initiation and development. Modern techniques and equipment are described in detail. Their high temporal and spatial resolution may be used to solve a number of problems concerning the short-term and microscopic aspects of discharges. A summary is given of a great deal of experimental data on the kinetics of vacuum breakdown. The authors used these results to identify a series of steps in the vacuum breakdown phenomenon. They were the first to discover and describe the explosive electron emission phenomenon and to show its fundamental role in the spark and the arc stages of a discharge. The information in this book may encourage the reader to design new experiments. The results presented may be applied to solve specific research or engineering problems.

Book Description
Mesyats' Pulsed Power provides in-depth coverage of the generation of pulsed electric power, electron and ion beams, and various types of pulsed electromagnetic radiation. The electric power that can be produced by the methods described ranges from 106 to 1014W for pulse durations of 10-10-10-7s. The book consists of nine parts containing 28 chapters, which deal with various aspects of pulsed power and high-power electronics and cover a concise theory of electric circuits as applied to nanosecond pulse technology; physics of fast processes occurring in electrical discharges in vacuum, gases, and liquids; phenomena in long lines; mechanisms of operation and designs of high-power gas-discharge, plasma, and semiconductor closing and opening switches as well as of high-power electric pulse generators using these switches; solid-state (semiconductor and magnetic) methods of production and transformation of nanosecond high-power pulses; and methods of production of high-power pulsed electron and ion beams. The closing part describes methods applied to produce high-power nanosecond pulsed X-rays, laser beams, microwaves, and ultrawideband electromagnetic radiation. This all-embracing book covers gas, laser, semiconductor, and magnetic circuit elements, the phenomenon of explosive electron emission discovered by the author, diodes of various types, including semiconductor diodes based on the SOS effect discovered with participation of the author, and methods of production of various types of high-power pulsed radiation.

Book Description
Pulsed power technology, in the simplest of terms, usually concerns the storage of electrical energy over relatively long times and then its rapid release over a comparatively short period. However, if we leave the definition at that, we miss a multitude of aspects that are important in the ultimate application of pulsed power. It is, in fact, the application of pulsed power technology to which this series of texts will be focused. Pulsed power in today's broader sense means "special power" as opposed to the tra ditional situation of high voltage impulse issues related to the utility industry. Since the pulsed power field is primarily application driven, it has principally an engineering flavor. Today' s applications span those from materials processing, such as metal forming by pulsed magnetic fields, to other varied applications, such as psy chedelic strobe lights or radar modulators. Very high peak power applications occur in research for inertial confinement fusion, the Strategic Defense Initiative and other historical defense uses. lri fact it is from this latter direction that pulsed power has real ized explosive growth over the past half century. Early thrusts were in electrically powered systems that simulated the environment or effects of nuclear weapons detonation. More recently it is being utilized as prime power sources for directed energy weapons, such as lasers, microwaves, particle beam weapons, and even mass drivers (kinetic energy weapons).

Book Description
This book presents the application of pulsed electrical discharges in water and water dispersions of metal nanoparticles in medicine (surgery, dentistry, and oncology), biology and ecology. The intensive electrical and shock waves represent a novel technique to destroy viruses and this way to prepare anti-virus vaccines. The method of pulsed electrical discharges in water allows to decontaminate water from almost all known bacteria and spores of fungi being present in human beings. The nanoparticles used are not genotoxic and mutagenic. This book is useful for researchers and graduate students.

Book Description
A phenomenological picture of pulsed electrical discharge in gas bubbles in water is produced by combining electrical, spectroscopic, and imaging methods. The discharge is generated by applying one microsecond long 5 to 20 kilovolt pulses between the needle and disk electrodes submerged in water. A gas bubble is generated at the tip of the needle electrode. The study includes detailed experimental investigation of the discharge in argon bubbles and a brief look at the discharge in oxygen bubbles. Imaging, electrical characteristics, and time-resolved optical emission data point to a fast streamer propagation mechanism and formation of a plasma channel in the bubble. Spectroscopic methods based on line intensity ratios and Boltzmann plots of line intensities of argon, atomic hydrogen, and argon ions and the examination of molecular emission bands from molecular nitrogen and hydroxyl radicals provide evidence of both fast beam-like electrons and slow thermalized ones with temperatures of 0.6-0.8 electron-volts. The collisional nature of plasma at atmospheric pressure affects the decay rates of optical emission. Spectroscopic study of rotational-vibrational bands of hydroxyl radical and molecular nitrogen gives vibrational and rotational excitation temperatures of the discharge of about 0.9 and 0.1 electron-volt, respectively. Imaging and electrical evidence show that discharge charge is deposited on the bubble wall and water serves as a dielectric barrier for the field strength and time scales of this experiment. Comparing the electrical and imaging information for consecutive pulses applied at a frequency of 1 Hz indicates that each discharge proceeds as an entirely new process with no memory of the previous discharge aside from long-lived chemical species, such as ozone and oxygen. Intermediate values for the discharge gap and pulse duration, low repetition rate, and unidirectional character of the applied voltage pulses make the discharge process here unique compared to the traditional corona or dielectric barrier discharges. These conditions make the experimental evidence presented in this work valuable for the advancement of modeling and the theoretical understanding of the discharge in bubbles in water.

Book Description
The book describes the main physical processes and phenomena in pulsed electric breakdown. The knowledge and the control of the electric breakdown of liquids is important not only for the insulation inside power systems but it is also used for the creation and information of high voltage and high current pulses. Such high-voltage micro- and nanosecond pulses find wide application in experimental physics, electro discharge technology, physics of dielectrics, radar detection and ranging, high-speed photography.
