Изучены процесс химической очистки поверхности ниобия перед сваркой, структура, механические и сверхпроводящие свойств получаемых с помощью электронно-лучевой сварки сварных соединений особочистого ниобия. Разработан метод создания одноячеечных 1,3 ГГц СВЧ-ниобиевых резонаторов, включающий гидроударную штамповку заготовок из листового материала, соединение отдельных компонентов между собой электронно-лучевой сваркой, финишную химическую обработку рабочей поверхности резонаторов. Приведены результаты ВЧ-испытаний изготовленного 1,3 ГГц одноячеечного ниобиевого резонатора, которые свидетельствуют о сохранении материалом резонатора высокой чистоты, сверхпроводящих свойств и соответствии геометрии заданным размерам.</p></abstract><trans-abstract xml:lang="en"><p>The analyses of important characteristics of high purity niobium were done. The results of a study of structure and mechanical properties of welding joints, superconducting characteristics of the material after joining of welded components of superconducting radio frequency cavities are presented. The manufacturing technology of SRF niobium cavity using liquid impact forging, electron beam welding and chemical polishing was developed. The paper also describes the results of testing of the SRF 1.3 GHz single-cell niobium cavity manufactured in the PTI NAS of Belarus.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">XFEL: The European X-Ray Free-Electron Laser.
