摘要

摘要: 該文利用多模穩(wěn)態(tài)非線性理論，研究損耗材料加載和導(dǎo)引中心半徑調(diào)節(jié)對回旋行波管穩(wěn)定性改善的效果。結(jié)果表明，隨著損耗材料電導(dǎo)率的減小返波振蕩強(qiáng)度逐漸減小直至完全消失，同時工作模式輸出功率顯著增大；適當(dāng)增大導(dǎo)引中心半徑后，完全抑制返波振蕩需要的損耗更小，可以減輕熱損耗散熱的困難，同時還能減小管子輸出性能對電導(dǎo)率變化的敏感性。

Abstract: In this paper, the effect of distributed loss loading and guiding center radius modifying on the stability of a TE11 mode Gyro-Traveling Wave Tube (Gyro-TWT) is studied by multimode steady-state method. The result shows that the output power of the backward oscillation mode keeps weaken till zero as the conductance of the lossy material reduces, while the output power of the working mode grows significantly. As guiding center radius increases, loss loading needed to suppress oscillation completely is weaker, which makes heat easier to dissipate. Besides, the increment of guiding center radius also makes the output characteristic less sensitive to conductance variation.
