Линейный ускоритель, состоящий из двух типов ускоряющих резонаторов: RFQ и IH-DTL, должен обеспечить ускорения протонного пучка с током до 100 мА до энергии 13 МэВ. При работе ускоритель подвергается тепловым нагрузкам, которые могут вывести его из рабочего режима, путем влияния термодеформаций его конструкции на рабочую частоту. С целью обеспечения стабильности электродинамических параметров ускоряющих структур, необходимо предусмотреть систему охлаждения, обеспечивающую термостабилизацию его конструкции. В работе представлены результаты расчета системы охлаждающих каналов в элементах конструкции резонаторов при работе ускорителя в импульсном режиме с коэффициентами заполнения (duty factor) 1–5%.</p></abstract><trans-abstract xml:lang="en"><p>A linear accelerator for the compact neutron source dedicated to applied research and industrial (DARIA) [<xref ref-type="bibr" rid="cit1">1</xref>] is under development at Kurchatov Complex of Theoretical and Experimental Physics, National Research Centre Kurchatov Institute. This accelerator consisting of RFQ and IH-DTL types of accelerating cavities should ensure the acceleration of a proton beam with a current up to 100 mA to an energy of 13 MeV. The operating accelerator is subjected to thermal loads, which can break its working regime due to the effect of thermal strains of its units on the working frequency. To ensure the stability of electrodynamical parameters of accelerating structures, a cooling system should be used to ensure the thermal stabilization of its design. The calculation of the system of cooling channels in elements of the design of cavities at the operation of the accelerator in the pulsed regime with a duty factor of 1–5%.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>система охлаждения</kwd><kwd>линейный ускоритель</kwd><kwd>нейтронный источник</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cooling system</kwd><kwd>linear accelerator</kwd><kwd>neutron source</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">Grigoriev S., Iashina E., Pavlov K. // J.
