| 摘 要： | 为实现低阻无箔运行,进一步增加现有高功率微波源输出功率和脉宽,给出了一种基于渡越辐射的低阻无箔高功率微波源的初步实验结果。主要对比分析了在铜介质片阴极和天鹅绒阴极以及不锈钢收集极和石墨收集极条件下器件的运行状况，分析了影响器件正常工作的可能原因，得出了在现有条件下天鹅绒阴极和石墨收集极最有利于器件运行的结论。初步的实验结果表明:降低强流相对论电子束的能量密度、选择更加合理的电子束收集方式，是实现该器件正常运行的重要手段。

| Abstract: | The article gives the preliminary experimental results of a foilless low-impedance transition-radiation oscillator. In the experiments, copper dielectric and polymer velvet are respectively adopted as explosive emission cathodes and stainless steel and graphite are respectively adopted as collectors of exiting electrons. The experimental results from various states are compared and some possible causes affecting device operation are analyzed. As indicated by the experimental results, the combination of velvet cathode and graphite collector is more advantageous to microwave generation. Dissipating the energy of an intense relativistic electron beam and choosing a proper manner to collect electrons are important to realizing the stable operation of the oscillator. |
