摘要

摘要: 该文利用多模稳态非线性理论，研究损耗材料加载和导引中心半径调节对回旋行波管稳定性改善的效果。结果表明，随着损耗材料电导率的减小返波振荡强度逐渐减小直至完全消失，同时工作模式输出功率显著增大；适当增大导引中心半径后，完全抑制返波振荡需要的损耗更小，可以减轻热损耗散热的困难，同时还能减小管子输出性能对电导率变化的敏感性。

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.
