Исследовано ускорение электронов, возникающее в результате взаимодействия ЛГ-пучков с заряженными частицами. Разработана теоретическая модель для объяснения лежащих в основе механизмов ускорения, дополненная численным моделированием. Проанализирована динамика электронов в структурированных электромагнитных полях ЛГ-пучка с выявлением характерного поведения ускорения вдоль направления распространения пучка. Показано, что орбитальный угловой момент и пространственная структура поля ЛГ-пучков позволяют осуществлять контролируемое и эффективное ускорение электронов.</p></abstract><trans-abstract xml:lang="en"><p>   The use of Laguerre–Gaussian (LG) laser beams in particle acceleration provides a promising pathway for advancing laser-driven acceleration schemes. We investigate electron acceleration resulting from the interaction of LG beams with charged particles. A comprehensive theoretical framework is formulated to elucidate the underlying acceleration mechanisms, complemented by detailed numerical simulations. The electron dynamics in the structured electromagnetic fields of the LG beam are systematically analyzed, revealing distinctive acceleration behavior along the direction of beam propagation. Our results demonstrate that the orbital angular momentum and spatial field structure of LG beams enable controlled and efficient electron acceleration. These findings highlight the potential of LG beams as a viable tool for tailored electron acceleration and contribute to the broader development of advanced laser-plasma and laser-based acceleration techniques.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ускорение электронов</kwd><kwd>математическое моделирование</kwd><kwd>лазерно-электронное взаимодействие</kwd><kwd>релятивистская динамика электронов</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electron acceleration</kwd><kwd>mathematical modeling</kwd><kwd>laser-electron interaction</kwd><kwd>relativistic electron dynamics</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Внешнее финансирование не привлекается</funding-statement><funding-statement xml:lang="en">No external funding is involved</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">C.
