摘要

本文对采用交错双叶片慢波结构(SDV-SWS)的高输出功率超宽g波段行波管的研制进行了深入研究。研究发现，随着周期的增加，波束相互作用的稳定性对实现高功率和高增益至关重要。为此，提出了两种对应于Bragg反射器和两级SDV-SWS的方案来抑制反射行波与非工作模式振荡的相互作用。90周期片波束SDV-TWT可实现580 ~ 590w的峰值功率，对应的增益约40.6dB，电子效率为5.5 ~ 5.6%，g频段带宽为35 ~ 70ghz。

Investigation on Stability of the Beam-wave Interactions for G-band Staggered Double Vane TWT

The development of the high output power and ultra-wide G-band travelling wave tube (TWT) using staggered double vane slow wave structure (SDV-SWS) are investigated thoroughly in this paper. It is found that the stability of the beam wave interaction is crucial with the increase of the periods of TWT to achieve the high power and gain. Thus, two kinds of scheme, which are corresponding to Bragg reflector and two stage SDV-SWS are put forward to suppress the reflection travelling wave interaction with non-working mode oscillating. The 580-590W peak power can be achieved with the 90 periods sheet beam SDV-TWT, which is corresponding the gain of about 40.6dB, the electronic efficiency of 5.5-5.6%, and the bandwidth of 35-70GHz in G-band.
