Такая процедура требует наличия особой магнитной группирующей системы. Настоящая статья представляет собой общий обзор разработки нового магнитного группирователя. Обзор состоит из описания схемы группирователя, результатов моделирования магнитного поля и расчета опорной траектории релятивистских электронов, а также конструкции поворотных магнитов. Группирователь обеспечивает сильную зависимость времени пролета от энергии частицы и, таким образом, способен группировать относительно длинные сгустки в короткие. Другой его особенностью является то, что все электронно-оптические элементы данного устройства сделаны на постоянных магнитах.</p></abstract><trans-abstract xml:lang="en"><p>Generation of short electron bunches with high peak current is of great importance for different research and technological applications. Such generation requires a special bunching magnetic system. The paper is an overview of the development of a new magnetic buncher. It consists of the buncher scheme description, the results of magnetic field modeling and reference particle trajectory calculation for the relativistic electrons, and of the description of bending magnets. The buncher provides a strong dependence of the time of flight on the particle energy and thus is capable to bunch relatively long bunches to short ones. Another feature of the buncher is that all electron-optical elements has been made of permanent magnets.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>короткие электронные сгустки</kwd><kwd>электронно-оптические системы</kwd><kwd>фокусирующие магниты</kwd><kwd>постоянные магниты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Short electron bunches</kwd><kwd>electron-optical systems</kwd><kwd>focusing magnets</kwd><kwd>permanent magnets</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">This work was supported by grant 21-12-00207 of the Russian Science Foundation..</funding-statement><funding-statement xml:lang="en">This work was supported by grant 21-12-00207 of the Russian Science Foundation.</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">Skrinsky A.
