摘要

真空电子器件因其高频率和高功率的特性而成为许多应用领域的关键器件。为了利用100GHz以上的频率，提出了一种基于SWS带边附近区域相互作用的小型大功率辐射源SWS带边振荡器(SWSBO)。由于带边附近的阻抗变得非常大，可以发生强相互作用。SWSBO的概念已经成功地用折叠波导SWS进行了实验验证。实验f波段样机在23.1kV电压和150mA电流下，最大脉冲输出功率为32W，振荡频率为124.44GHz。

SWS band-edge oscillator

Vacuum electron devices are key devices for many applications due to their high frequency and high power characteristics. To exploit the frequency above 100GHz, a SWS band-edge oscillator (SWSBO) is proposed for a compact source of high-power radiation based on interaction in the region near band-edge of SWS. Because the impedance near band-edge becomes so great that strong interaction can occur. The concept of SWSBO has been successfully demonstrated experimentally using folded waveguide SWS. The experimental F-band prototype reaches maximum pulsed output power of 32W and the oscillator frequency of 124.44GHz with the voltage of 23.1kV and the current of 150mA, respectively.
