论述了在Sinus-700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8 mm,磁场的大小为1.75 T,二极管电压的大小为700 KV,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9.18 GHz,微波功率为1.5 Gw,脉宽为26ns,效率达31％左右。 The experimental research of X-band transition-tube oscillator on Sinus-700 accelerator is discussed. In the experiment, the accelerator was first adjusted to make it run stably. Then the parameters that affected the operation of the device were debugged to get the more suitable values ​​of each parameter, of which the length of 1/4 wavelength support was 8 mm, The size of the magnetic field is 1.75 T, the diode voltage is 700 KV, and the diode cathode structure is a rounded ring cathode. Finally, the microwave frequency is 9.18 GHz, the microwave power is 1.5 Gw, the pulse width is 26 ns and the efficiency is about 31% .
