摘要
设计和测试了内嵌准光系统的94 GH z回旋管,该系统主要用于研究毫米波辐射的非致命生物效应。为了减少大功率高频下的回旋管壁面加热问题,选择TE+6,2模式作为工作模式。对于高阶模式,存在更多相邻模式,因此模式竞争会影响实验的稳定性和有效的可操作性。渐变腔已被设计为抑制单个腔中的模式竞争。另外,具有低衍射准光模式变换器的功率转换效率为98.54%。实验结果表明,回旋管输出功率为50.9 kW,效率为34.3%。对于非致死的生物效应研究,整体设计方案达到了预期的效果。
The design and experiment of 94 GHz gyrotron with an inside quasi-optical system for the non-lethal biological effects of millimeter wave radiation are presented in this paper.The reason we chose TE+6,2 mode as the experimental working mode is to reduce the wall heating problem at high power and high frequency.For a highorder mode,there are more neighboring modes,so mode competition affects the stability and effective operability of the experiment.The gradually tapered cavity has been designed to suppress mode competition in single cavities.In addition,the power conversion efficiency of the quasi-optical mode converter with low diffraction is98.54%.The experimental results confirm that the output power of 50.9 kW is obtained with efficiency of34.3%.For the non-lethal biological effects,we can draw the conclusion that the overall scheme can achieved the expected results.
