| 中文摘要 | 作为小型化和紧凑型的高功率微波源,磁绝缘线振荡器(MILO)在过去十几年里得到了广泛的研究和发展.在大多数研究中,最低的对称模一直被当作器件的主模.然而,由于结构的对称性或者电子发射均匀度不理想等原因,很容易激励起非对称模式.计算了MILO同轴结构中同时包含对称模和非对称模的本征方程.在此基础上,通过对结构的优化设计,提出了一种HEM11模工作的MILO,并开展了原理性实验.在二极管的电压为480kV,电流为39kA条件下得到了功率为1.2GW,脉冲宽度为40ns的微波输出,功率转换效率约为6.5%,微波频率为1.98 GHz,模式为HEM11模.; Coaxial disk-loaded waveguide has been widely used in magnetically insulated transmission line oscillators(MILO).Although TM_00 mode is assumed to be its main mode,the asymmetric mode might be excited by slight asymmetry of the structure,asymmetric emission of the beam,or both.So the research on asymmetric mode in coaxial disk-loaded waveguide is necessary.The general eigen equation with both symmetric and asymmetric modes in coaxial disk-loaded slow-wave structures is theoretically analyzed.Then,a HEM_11 mode working MILO is designed and a tentative experiment is carried out to test its performance.Employing an electron beam of about 480 kV and 39 kA,HEM_11 mode working MILO generates a high power microwave output of about 1.2 GW with 40 ns pulse duration at 1.98 GHz.The power conversion efficiency is about 6.5% and the generated microwave mode is TE_11 in the coaxial output region. |
