Abstract

The scale of human economic activity and the specificity of modern technological processes used in industry, especially in chemical industry and metallurgy, require special measures for environment protection. For practical purposes, linear electron accelerators operating in pulsed mode are currently used. Such accelerators may have sufficient beam power for efficient use in the industry and for environment protection. This paper shows the fundamental possibility of leading an electron beam by own high-frequency fields of accelerating resonators in linear accelerators with standing wave made on the basis of bi-periodical slow-wave structures. The results of numerical calculation of electrons dynamics with various initial conditions have been shown. The obtained results have been used to create a three-section accelerator, for which the calculated and experimental data have been shown. The performed experimental studies have confirmed the possibility of creating a standing wave linear accelerator without an external magnetic focusing system with the output beam diameter not exceeding5 mm. The results of beam dynamics calculations have been experimentally confirmed.
