Для базовых измерений тока пучка и проведения настроечных процедур в низкоэнергетической части ускорителя был разработан широкоапертурный водоохлаждаемый цилиндр Фарадея. В данной работе представлены конструктивные особенности, оценки тепловых нагрузок в типичных рабочих режимах и экспериментальные результаты испытаний цилиндра на высокоинтенсивном пучке протонов, а также описаны особенности проектирования подобных устройств с учетом влияния пространственного заряда пучка на результаты измерений.</p></abstract><trans-abstract xml:lang="en"><p>One of the main problems for beam diagnostics in the projected linear proton accelerator for the DARIA compact neutron source is the high pulse and average beam power combined with a relatively low energy, that significantly limits the choice of possible diagnostic instruments and methods. For basic beam current measurements and tuning procedures in the low-energy part of the accelerator, a wide-aperture water-cooled Faraday cup was developed. This paper presents design features, estimations of thermal loads during typical operation and experimental results of the cup tests at a high-intensity proton beam, also the design features of such devices are described, considering the influence of the beam space charge on the measurement results.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>линейный ускоритель протонов</kwd><kwd>диагностика пучка</kwd><kwd>цилиндр Фарадея</kwd></kwd-group><kwd-group xml:lang="en"><kwd>linear proton accelerator</kwd><kwd>beam instrumentation and diagnostics</kwd><kwd>Faraday cup</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа поддержана Министерством науки и высшего образования Российской Федерации в рамках работ по договору № 075-15-2021-1358 от 12 октября 2021 г.</funding-statement><funding-statement xml:lang="en">The work carried out by the Ministry of Science and Higher Education of the Russian Federation under Contract No. 075-15-2021-1358 dated October 12, 2021.</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">Kropachev G. et al.
