摘要
Abstract
[Background]Superradiant relativistic backward wave oscillators(SR-RBWOs)typically utilize electron beams with a pulse width of several nanoseconds.The required pulse source features small volume and light weight,which provides a feasible technical approach and implementation scheme for the development of compact high-power microwave systems.Superradiant microwave pulses are characterized by a fast-rising edge,high peak power,and wide bandwidth,which are expected to better satisfy the application requirements in complex electromagnetic environments.[Purpose]In this paper,an X-band SR-RBWO with extended slow wave structure operating at a strong magnetic field is designed,which can simultaneously achieve stable operation and high conversion efficiency.[Methods]And experimental investigations were carried out using a compact Tesla-type pulse source experimental platform.[Results]The experimental results demonstrate that under the conditions of a diode voltage of 283 kV and a current of 3.25 kA,a pulse rise time of 1.8 ns,and a guiding magnetic field of 3 T,the generated SR pulse achieves a power of 840 MW with a power conversion factor of 0.91.The pulse full-width at half-maximum(FWHM)is 1.2 ns,the operating center frequency of the device is 10 GHz,and the microwave is radiated in the TM01 mode.Stable operation is realized at a repetition frequency of 50 Hz.[Conclusions]The experimental results provided a reference for further experimental verification of low magnetic field SR-RBWO.关键词
