The staggered double-grating slow-wave stricture with wideband input/output coupling structures was designed and optimized and its high-frequency electromagnetic parameters were calculated. The results of 3D particle-in-cell simulation of beam-wave interaction in the TWT are presented. Gain over 30 dB in the 25-GHz frequency band was obtained. A sample of an electron gun with an impregnated cathode, focusing electrode, and anode, providing the formation of a sheet electron beam with a high-aspect ratio and a current of 0.1 A, was designed and fabricated. The design of the vacuum window is presented, and the technology of its fabrication is discussed.</p></abstract><trans-abstract xml:lang="ru"><p>Приведены результаты разработки лампы бегущей волны <italic>O</italic>-типа W-диапазона с ленточным электронным пучком. Разработана и оптимизирована конструкция замедляющей системы в виде сдвоенной гребенки с широкополосными согласующими устройствами ввода–вывода, проведен расчет ее электродинамических параметров. Представлены результаты трехмерного компьютерного моделирования процессов усиления в ЛБВ методом частиц в ячейке. Получен коэффициент усиления, превышающий 30 дБ в полосе частот около 25 ГГц. Разработан и изготовлен макет электронной пушки с прессованным импрегнированным катодом, фокусирующим электродом и анодом, обеспечивающий формирование ленточного электронного пучка с высокоаспектным соотношением сторон и током 0.1 А. Представлена конструкция вакуумного окна, обсуждается технология его изготовления.</p></trans-abstract><kwd-group xml:lang="en"><kwd>millimeter band</kwd><kwd>traveling-wave tube</kwd><kwd>slow-wave structure</kwd><kwd>staggered double-grating</kwd><kwd>electron gun</kwd><kwd>sheet electron beam</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>миллиметровый диапазон</kwd><kwd>лампа бегущей волны</kwd><kwd>замедляющая система</kwd><kwd>сдвоенная гребенка</kwd><kwd>электронная пушка</kwd><kwd>ленточный электронный пучок</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap></funding-source><award-id>22-49-02017</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Григорьев А.Д.
