| 摘 要： | 采取减小阴极杆半径和长度、阴阳极间隙、叶片的长度和厚度及慢波结构周期的办法构造了一种紧凑型磁绝缘线性振荡器（MILO），并用2.5维全电磁PIC方法对这一器件进行了粒子模拟研究。该装置主频为1.9GHz，饱和后平均输出功率达5.4GW，束波转换效率达12％。紧凑型MILO结构能避免电击穿，电子束发射的对称性较易控制。

| Abstract: | A compact L-band magnetically insulated transmission line oscillator (MILO) is configured with the reduction of the radius and the length of the cathode, the anode-cathode gap, the length and the thickness of the vanes and the period of the slow-wave structure. With the use of a 2.5 dimensional fully electromagnetic particle-in-cell code, high power microwave is generated from the device with the average output power of 5.5GW, the frequency of 1.9GHz and the efficiency of 12%. Breakdown can be avoided in the compact MILO and the symmetry of beam emission can be controlled easily. |
