摘　　要：螺旋线慢波组件的散热性能是影响行波管输出功率、工作稳定性及可靠性的重要因素.金刚石材料具有极高的导热性能,将金刚石材料应用于螺旋线慢波组件的制备,可以在一定程度上改善组件散热性能.本文计算模拟分析了沉积金刚石薄膜的夹持杆、沉积金刚石薄膜的螺旋线以及金刚石夹持杆对慢波组件散热性能的影响.结合实验和模拟对比研究,使计算机仿真与实验测试紧密关联,提高了计算机模拟研究准确性,为金刚石材料在慢波组件中的应用提供了重要的参考依据.The heat dissipation capability of the slow-wave structure （SWS） of the traveling-wave tube （TWT） is an important influencing factor that restricts the increase of the output power, the stability, and the reliability. Due to several unique and fascinating characteristics, the diamond material has been employed in the SWS manufacture to enhance the thermal conduction to a certain extent. The influences of the supporting rods deposited with diamond film, the helix deposited with diamond film, and the diamond supporting rods on the heat dissipation capability have been studied using theoretical, simulation, and experimental methods. This method is closely associated with the computer simulation in experimental test and increases the simulation accuracy. Valuable conclusions have been obtained.
