The book discusses explosive pulsed power systems and their applications. It consists of 7 chapters. The first five describe the basic physics of these sources and their ancillary equipment. These chapters are based on a manual for training engineers in Russia. Chapter 6 is a description of codes and methodologies used at loughborough university in the UK to build flux compressors. Chapter 7 covers two specific applications: high power lasers and high power microwave sources. The book introduces all types of explosive power sources and their ancillary equipment, describes the procedures required to build them, and specific applications.
