High Speed Pulse Technology, Volume 1: Capacitor Discharges - Magnetohydrodynamics - X-Rays - Ultrasonics deals with the theoretical and engineering problems that arise in the capacitor discharge technique.

This book discusses the characteristics of dielectric material, symmetrical switch tubes with mercury filling, and compensation conductor forms. The transformed discharge for highest current peaks, ignition transformer for internal combustion engines, and X-ray irradiation of subjects in mechanical motion are also elaborated. This text likewise covers the transformed capacitor discharge in welding engineering, application of strong magnetic shock fields in nuclear physics, and shock sound by underwater capacitor discharges. Other topics include the shaping metals by electrical explosion shock wave and electro-erosion machining of metals.

This volume is recommended for electrical engineering and physics students.
