В процессе взаимодействия заряженных частиц с элементами вакуумной камеры накопителя пучок наводит поля, которые могут приводить к неустойчивостям, ограничивающим либо заряд в сгустке (односгустковые неустойчивости), либо суммарный ток накапливаемого пучка (многосгустковые неустойчивости). Проведена оценка порогов возникновения односгустковых неустойчивостей в накопительном кольце.</p></abstract><trans-abstract xml:lang="en"><p>Collective effects are studied in the fourth-generation synchrotron radiation source USSR (the SILA project) currently being designed. During the interaction of charged particles with the elements of the vacuum chamber of the storage ring, the beam induces wakefields that can lead to instabilities that limit either the charge in the bunch (single-bunch instabilities) or the total current of the accumulated beam (multibunch instabilities). The thresholds for the occurrence of single-bunch instabilities are evaluated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>источник синхротронного излучения</kwd><kwd>коллайдер</kwd><kwd>неустойчивости пучка</kwd><kwd>микроволновая неустойчивость</kwd><kwd>эмиттанс</kwd><kwd>импеданс</kwd><kwd>моделирование</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">Bitbucket repositories: https://bitbucket.org/cremlinplus-wp4-task3</mixed-citation><mixed-citation xml:lang="en">Bitbucket repositories: https://bitbucket.org/cremlinplus-wp4-task3</mixed-citation></citation-alternatives></ref><ref id="cit2"><label>2</label><citation-alternatives><mixed-citation xml:lang="ru">Code ECHO: https://echo4d.de/</mixed-citation><mixed-citation xml:lang="en">Code ECHO: https://echo4d.de/</mixed-citation></citation-alternatives></ref><ref id="cit3"><label>3</label><citation-alternatives><mixed-citation xml:lang="ru">W.B.
