摘要: 提出一种新型相对论返波管 同轴引出相对论返波管结构。首先，利用KARAT软件对这种结构进行了2.5维全电磁粒子数值模拟，经过参数调整，输出的微波脉冲功率为2.0GW，微波频率为9.28 GHz，转换效率达45%。并在模拟中对电子束与电磁波的作用过程进行了跟踪和分析；然后利用SUPERFISH软件对此结构中的场分布进行了计算，结合PIC模拟结果，初步证明了由于内导体的引入改变了返波管末端的反射，有利于电子束与电磁波的能量交换。Abstract: This paper brings forth a new relativistic backward-wave oscillator with axial extracting. Numerical simulation is conducted using KARAT code. This simulation produces a microwave pulse power of 2.0GW at 9.28GHz for 730 kV, 6kA injecting beam. Power transform efficiency of 45% is obtained. The interaction between beam and slow wave structure is tracked and analyzed. SUPERFISH code is used to calculate axial electric field distribution, and the results shows that the relativistic backward-wave oscillator with axial extracting has the advantage of increasing efficiency.
