Обогащение спектра излучения электронного генератора с пассивной синхронизацией мод в жестком режиме возбуждения
Аннотация
Анализируется возможность существенного обогащения спектра выходного излучения электронного генератора с пассивной синхронизацией мод, включающего винтовую гиро-ЛБВ миллиметрового диапазона и циклотронно-резонансный поглотитель. Для этого необходимо осуществить жесткий запуск генератора, когда по цепи обратной связи циркулирует единственный электромагнитный импульс, тогда как в мягком режиме возбуждения таких импульсов много. Исследована возможность жесткого запуска генератора с центральной частотой 33.5 ГГц субнаносекундным импульсом от ЛОВ с частотой 38 ГГц, запитываемой драйвером РАДАН. Полученные данные будут использованы в экспериментах по реализации жесткого режима генерации мощных субнаносекундных импульсов на основе пассивной синхронизацией мод.
- генерация коротких импульсов

Abstract (in English)
Enrichment of the radiation spectrum of an electron generator with passive mode locking in a hard excitation regime
In this paper, we analyze the possibility of significant enrichment of the output radiation spectrum of an electronic oscillator with passive mode locking, including a helical gyro-TWT of the millimeter range and a cyclotron resonance absorber. To do this, it is necessary to implement a hard start of the oscillator, when a single electromagnetic pulse circulates along the feedback circuit, while in the soft excitation regime there are many such pulses. The possibility of a hard start of the oscillator with a central frequency of 33.5 GHz by a subnanosecond pulse at a frequency of 38 GHz from a single-pass BWO fed by a RADAN driver is investigated. The obtained data will be used in experiments on the implementation of a hard regime of generating powerful subnanosecond pulses based on passive mode locking.
