Расчеты оптимальных конструкций гиротронных ламп бегущей волны (гиро-ЛБВ), представленные в статье, проведены с использованием компьютерной программы Gyro-K с помощью методики преобразования координат, позволяющей существенно сократить время расчетов гирорезонансных приборов за счет сведения трехмерной задачи возбуждения нерегулярного волновода к одномерной. Рассмотрены два варианта создания гиро-ЛБВ на моде волны TE02: первый – работающий на первой гармонике гирочастоты, второй – умножитель частоты. Приведены достижимые характеристики приборов в терагерцевом диапазоне частот – такие как полосы усиления, КПД, коэффициенты усиления и распределения высокочастотных полей в продольном и поперечном сечениях. Гиро-ЛБВ-умножитель частоты обладает полосой усиления 7,2 %, КПД – 17 % и коэффициентом усиления 30 Дб.</p></abstract><trans-abstract xml:lang="en"><p>Gyrotron-type amplifiers are being developed for various applications requiring high power in the millimeter wavelength range. Calculations of the optimal designs of gyrotron traveling wave tubes (gyro-TWTs), presented in the article, were carried out using the Gyro-K computer program using a coordinate transformation technique, which made it possible to significantly reduce the calculation time of gyroresonance devices by reducing the three-dimensional problem of excitation of an irregular waveguide to a one-dimensional one. Two options for creating a gyro-TWT using the TE02 wave mode are considered: the first one is operating at the first harmonic of   the gyrofrequency, the second is a frequency multiplier. The achievable characteristics of devices in the terahertz frequency range are presented, such as gain bands, efficiency, gain factors and distributions of high-frequency fields in longitudinal and transverse sections. The gyro-TWT frequency multiplier has a gain bandwidth of  7.2 %, an efficiency of 17 %, and a gain of 30 dB.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гиротронная лампа бегущей волны</kwd><kwd>миллиметровый диапазон</kwd><kwd>длина волны</kwd><kwd>умножитель частоты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>traveling wave gyrotron tube</kwd><kwd>millimeter wave</kwd><kwd>wavelength</kwd><kwd>frequency multiplier</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">Thumm, M.
