Монохроматор М833 был использован для регистрации спектра излучения плазменного потока. Высокоскоростная видеосъемка осуществлялась со скоростью 640 000 кадров/с с использованием CMOS-камеры Phantom VEO710S. Приведены результаты измерений средней скорости потока, полученные при рабочем давлении газа 2⋅10-2 Торр, емкости и напряжении конденсаторной батареи 400 мкФ и 4 кВ. Полученные результаты двумя независимыми методами были сравнены между собой. Аргон использовался в качестве рабочего газа в экспериментах. Показано, что при использовании первого метода значение скорости плазменного потока составляет 12,5⋅103  м/сек, а при использовании второго метода значение скорости плазменного потока составляет 16,7⋅103  м/сек. По этим данным можно видеть, что измеренные значения скорости потока имеют небольшое расхождение. Таким образом, было установлено, что методы высокоскоростной видеосъемки и доплеровского сдвига дают в пределах ошибок измерений сопоставимые оценки скорости движения потока. С точки зрения практического применения определение значение скорости плазменного потока имеет очень большое значение.</p></abstract><trans-abstract xml:lang="en"><p>The paper considers two independent methods for measuring the velocity of the plasma flow generated in the PV-7 pulsed plasma accelerator: a method based on observation and evaluation of the Doppler shift of spectral lines, and a method of high-speed visualization of plasma motion. To record the plasma flow radiation spectrum, a monochromator M833 was used. High-speed video recording was carried out at 640,000 fps using a Phantom VEO710S CMOS camera. The results of measurements of the average flow velocity obtained at a working gas pressure of 2⋅10-2 Torr, capacitance and voltage of the capacitor bank of 400 μF and 4 kV are presented. The results obtained by two independent methods were compared with each other. Argon was used as the working gas in the experiments. It is shown that the value of the plasma flow velocity estimated by the first method is 12.5 m/s, and the value of the plasma flow velocity estimated by the second method is 16.7 m/s. From these data the measured flow velocity values have a small discrepancy. Thus, it has been established that high-speed video recording and Doppler shift methods make it possible to obtain comparable estimates of flow velocity within the measurement errors. Determining the magnitude of the plasma flow velocity is of great practical importance.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>импульсный плазменный ускоритель</kwd><kwd>высокоскоростная видеосъемка</kwd><kwd>доплеровский сдвиг</kwd><kwd>плазменный поток</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pulsed plasma accelerator</kwd><kwd>high-speed video recording</kwd><kwd>Doppler shift</kwd><kwd>plasma flow</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа финансировалась Министерством науки и высшего образования Республики Казахстан в рамках проекта No BR18574080 «Исследование фундаментальных и прикладных проблем физики плазмы, плазмоподобных сред для целей решения задач современной энергетики и получения новых функциональных материалов».</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">Linsmeier Ch., Unterberg B., Coenen J.W., Doerner R.P., Greuner H., Kreter A., Linke J., Maier H.
