Показано, что при использовании данного метода доля трехкратно и двукратно заряженных ионов тория по отношению к однократно заряженным ионам превосходит аналогичные значения для метода лазерной абляции, применяемого для их получения в лабораториях США и Германии. Метод электронно-лучевого испарения положен в основу разработанного комплекса оптической спектроскопии сверхвысокого разрешения.</p></abstract><trans-abstract xml:lang="en"><p>A laboratory prototype of a complex of optical spectroscopy of multiple-charged thorium ions for development of nuclear frequency standard is presented, as well as preliminary experimental research on generation of single-, double-, and triple-charged ions from solid compounds of thorium nitrate (IV) by electron beam evaporation are carried out. It is shown that the ratio of triple- and double-charged ions to single-charged ions produced by this technique exceeds values obtained by the laser ablation method in laboratories of the U.S. and Germany. Electron beam evaporation technique is the basis of the developed complex of optical high-resolution spectroscopy.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ионная ловушка Пауля</kwd><kwd>одномерные структуры</kwd><kwd>масс-спектрометрия</kwd><kwd>источник ионов</kwd><kwd>ядерный стандарт частоты</kwd><kwd>многозарядные ионы тория</kwd><kwd>ion Paul trap</kwd><kwd>one-dimensional structures</kwd><kwd>mass-spectrometry</kwd><kwd>ion source</kwd><kwd>nuclear frequency standard</kwd><kwd>multiple-charged thorium ions</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Phillips W.
