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.

Isak Beilis is a Professor in the Faculty of Engineering at Tel Aviv University. He received his PhD and Doctor of Science in Physics and mathematics from the Academy of Sciences, Moscow, and subsequently held positions at  Lomonosov University, Moscow, the Weizmann Institute for Science, joining Tel Aviv University in 1992. He has held visiting positions at the University of Minnesota, Minneapolis, USA in 1996 and 1997, at the Max Planck Institute, Berlin, and the Istituto Nazionale di Fisica Nucleare, Italy. His research centers around physical phenomena in high-current electrical discharges, at the electrode surface and in near-electrode plasma. In 2018 he was awarded the Walter P. Dyke Award for his many important contributions to discharge physics.
