50’th anniversary of Industrial ELV Accelerators

The article highlights the 50-year development of ELV electron beam accelerators at the Budker Institute of Nuclear Physics for industrial applications. ELV accelerators are used primarily for radiation modification of polymers, such as cable insulation, and are known for their high reliability, ease of use, and adaptability to various industrial needs. The evolution of these accelerators is traced from early models with 20 kW power to modern versions reaching up to 100 kW, and even a unique 400 kW machine. The article also discusses the integration of automated systems and specialized equipment that enhance the efficiency and quality of radia- tion-chemical processes. Applications include a wide range of industries, from telecommunications to nuclear power, where reliability under harsh conditions is essential. Despite past challenges, such as economic disrup- tions, the production of ELV accelerators continues to thrive, with over 220 units delivered worldwide. The institute is focused on advancing these technologies to meet future demands.
