Описаны условия резонансного взаимодействия ИЦР-волны с частицами плазмы, а также основные механизмы формирования плазмы с помощью ИЦР-волн. Представлены результаты экспериментов по предыонизации, в которых варьировались частота генератора, уровень тороидального магнитного поля, состав рабочего газа. Показано, что на токамаке МИФИСТ-0 с помощью ИЦР-ионизации возможно получить стабильную низкотемпературную плазму.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results of experimental studies on the use of RF waves in the ion cyclotron resonance (ICR) frequency range for plasma preionization at the small spherical tokamak MEPhIST-0. The conditions of resonant interaction of the ICR wave with plasma particles, as well as the main mechanisms of plasma formation using ICR waves are described. The results of experiments on preionization are presented, in which the generator frequency, the level of the toroidal magnetic field, and the composition of the working gas were varied. It is shown that stable low-temperature plasma can be obtained at the MIFIST-0 tokamak using ICR ionization.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ион-циклотронный резонанс</kwd><kwd>токамаки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ion-cyclotron resonance</kwd><kwd>tokamaks</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке НИР “Исследования в области взаимодействия плазмы с обращенными к плазме элементами на учебно-демонстрационной установке типа “токамак” в НИЯУ МИФИ с привлечением студентов и аспирантов”, выполняемого в рамках федерального проекта “Технологии термоядерной энергетики” национального проекта “Новые атомные и энергетические технологии”.</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">Kingham D., Gryaznevich M. // Phys.
