Semitransparent travelling-wave tube

Изобретение относится к области электронных приборов СВЧ, в частности к лампам бегущей волны. Лампа бегущей волны с вводом и выводом энергии, содержащими передающие линии волноводного типа, с пространством взаимодействия в виде замедляющей системы, содержащей спираль, опорные диэлектрические стержни и металлический экран, с локальным поглотителем, выполненным на основе резистивной пленки, размещенной на опорных диэлектрических стержнях. Резистивная пленка поглотителя наносится так, что отсутствует на поверхности диэлектрических стержней, касающейся спирали, и на части поверхности боковых сторон и присутствует на оставшейся части боковых сторон диэлектрических стержней. Таким способом достигается то, что затухание, вносимое поглотителем на нижних частотах, больше, чем на верхних частотах. Перепад затухания определяется, прежде всего, зазором между резистивной пленкой и спиралью. Подобрав величину зазора, можно добиться того, что уменьшение КПД за счет введения поглотителя будет минимальным, а вносимое затухание - достаточным для обеспечения устойчивости к самовозбуждению. Оптимальный зазор составляет от 0,3 до 0,6 высоты диэлектрического стержня для разных конструкций ЛБВ. Технический результат - улучшение выходных характеристик ЛБВ при обеспечении устойчивости к самовозбуждению, в том числе на частоте отсечки волноводов.1 з.п. ф-лы, 7 ил.

Collector with multi-stage recovery for an electronic gyrotron-type uhf apparatus

FIELD: electronics. SUBSTANCE: invention relates to electronic technology, namely to collectors with energy recovery in electro-vacuum microwave devices. The technical result is an increase in total efficiency by increasing the efficiency of multi-stage recovery and reducing the current reflected from the collector, and increasing the service life of the device by reducing the thermal load on the collector electrodes. To create an azimuthal magnetic field, a toroidal solenoid is used, the end conductors of which are assembled into bundles from the side from which the electron flow enters the collector to increase the flow of electrons passing into the recovery area. EFFECT: increase in the efficiency of recovery and a decrease in the flow of electrons reflected from the collector is achieved by reducing the spread of the radial position of the leading centers of the electron trajectories at optimal parameters of the toroidal solenoid, as well as through the use of a partitioned electron flow. 3 cl, 7 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 761 460 C1 (51) МПК H01J 23/027 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК H01J 23/0275 (2021.08) (21)(22) Заявка: 2020141826, 17.12.2020 (24) Дата начала отсчета срока действия патента: 08.12.2021 Приоритет(ы): (22) Дата подачи заявки: 17.12.2020 (45) Опубликовано: 08.12.2021 Бюл. № 34 2 7 6 1 4 6 0 R U (56) Список документов, цитированных в отчете о поиске: WU C., Gyrotron multistage depressed collector based on E x B drift concept using azimuthal electric field.
