Рассмотрены вопросы выбора оптимальной длины ускоряющих зазоров, геометрии трубок дрейфа и системы крепления трубок дрейфа с учетом ограничений на величину высокочастотных потерь в стенках резонатора и обеспечения распределения поля на оси, при котором величина поля в крайних ускоряющих зазорах составляет не менее 50 % от величины поля в центральных зазорах.</p></abstract><trans-abstract xml:lang="en"><p>   The paper presents the results of the development of short five-band accelerating structures of IH-type with a fixed length of accelerating gaps, calculated at a frequency of 80 MHz and velocities of 0.06 c and 0.1 с. The issues of choosing the optimal length of accelerating gaps, the geometry of drift tubes and the system of fixing drift tubes, taking into account restrictions on the magnitude of high-frequency losses in the walls of the resonator and ensuring the field distribution on the axis, at which the field value in the extreme accelerating gaps is at least 50 % of the field value in the central gaps, are considered.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ускоряющие структуры</kwd><kwd>ускоряющие зазоры</kwd><kwd>стенки резонаторов</kwd><kwd>резонаторы IH-типа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>accelerating structures</kwd><kwd>accelerating gaps</kwd><kwd>cavity walls</kwd><kwd>IH-type cavities</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">Kurennoy S., Rybarcyk L. and Wangler T. // Proc.
