论述了在sinus 70 0加速器上进行的X波段渡越管振荡器的实验研究 .在实验中 ,首先对加速器进行了调节 ,使其能够稳定运行 ;然后对影响器件运行的各个参数进行了调试 ,得到各参数的比较合适的值 ,其中 1 4波长支撑的长度为 8mm、磁场的大小为 1 85T、二极管电压的大小为 70 0kV、二极管阴极结构为倒圆的环形阴极头 ,最后得到微波频率为 9 18GHz ,微波功率为 1 5GW ,脉宽为2 6ns ,效率达 31%左右 . The experimental research of X-band transition-tube oscillator on sinus 70 0 accelerator is described in this paper.In the experiment, the accelerator is first adjusted so that it can run stably, and then the parameters that affect the operation of the device are debugged, Get the more appropriate value of each parameter, of which the length of 14 wavelength support is 8mm, the size of the magnetic field is 1 85T, the size of the diode voltage is 70 0kV, the diode cathode structure is round cathode cathode, and finally get the microwave frequency 9 18GHz, microwave power of 15GW, pulse width of 26ns, the efficiency of about 31%.
