Pulsed power-driven high-power microwave sources

Abstract

The advent of pulsed power technology in the 1960s has enabled the development of very high peak power sources of electromagnetic radiation in the microwave and millimeter wave bands of the electromagnetic spectrum. Such sources have applications in plasma physics, particle acceleration techniques, fusion energy research, high-power radars, and communications, to name just a few. This article describes recent ongoing activity in this field in both Russia and the United States. The overview of research in Russia focuses on high-power microwave (HPM) sources that are powered using SINUS accelerators, which were developed at the Institute of High Current Electronics. The overview of research in the United States focuses more broadly on recent accomplishments of a multidisciplinary university research initiative on HPM sources, which also involved close interactions with Department of Defense laboratories and industry. HPM sources described in this article have generated peak powers exceeding several gigawatts in pulse durations typically on the order of 100 ns in frequencies ranging from about 1 GHz to many tens of gigahertz.Keywords-High-power microwave (HPM), intense electron beams, pulsed power.

Review and Mechanism of the Thickness Effect of Solid Dielectrics

“…Solid dielectrics are widely used in high-voltage (HV) devices and pulsed power systems [ 1 , 2 , 3 , 4 , 5 , 6 ]. The breakdown characteristics of solid dielectrics have been researched for nearly 100 years.…”

Использование Двумерно-Периодических Замедляющих Структур На Основе Сверхразмерных Цилиндрических Волноводов Для Генерации Импульсов Черенковского Сверхизлучения Большой Пиковой Мощности

“…Представляет-ся также интересным анализ возможности использования двумерно-периодических замедляющих структур для генерации импульсов СИ в коротковолновой части миллиметрового диапазона. Экспериментальные исследования в данном направлении планируется развивать на базе ускорителей СИНУС [6] и РАДАН [8].…”

An Axial Foilless Diode Guided by Composite Magnetic Field for the Production of Relativistic Electron Beams

“…Foilless diode is widely used in high-power microwave generation [1][2][3], free-electron lasers [4], and magnetically confined plasma heating [5]. Since Friedman and Ury developed an electron beam injection gun guided by external magnetic field in 1970 [6,7], extensive work has been done in the past 50 years in producing high-power relativistic annular electron beams [8][9][10][11][12].…”
