Opis

Beams of accelerated particles are of particular importance in researching the structure of matter, for example, the structure of elementary particles and nature of nuclear forces. The present book reviews the problems concerned both with generation of accelerated particles and with application of electron beams for exerting chemical, thermal and other effects on matter. The book is designed for experts specializing in designing and servicing electron accelerators or developing new production processes with the use of accelerated particles.
