摘要
为面向前沿科学研究,介绍了WHMFC(Wuhan National High Magnetic Field Center)基于自研软件开发的太赫兹谐波回旋管平台,简述了平台的设计方案及实验系统.该平台已利用15 T超导磁体开展一系列相关实验,实现了二次谐波下TE8,5模式、基波下TE1,4、TE3,3等多种模式的输出与频率、功率测量,在14.81 T磁场下,测量得到了约800GHz的谐波辐射.进一步放宽磁场调节范围,测量到了工作在不同TE模式下的基波,频率涵盖了从217 GHz到381 GHz的较宽范围,功率达数十瓦到数百瓦不等.初步实验结果表明,所开发的回旋管平台在基波、谐波工作方式下均具有良好的输出能力.
Abstract
A terahertz harmonic gyrotron platform based on in-house software for advanced scientific research in Wuhan National High Magnetic Field Center(WHMFC)is introduced,and the design scheme and experimental system of the platform are briefly described.The platform has been used to conduct a se-ries of related experiments with a 15T superconducting magnet,the output is achieved,the frequency and power are measured under various modes including the second harmonic under the TE8,5 mode,and the fundamental mode under TE1,4,TE3,3 modes.Under a 14.81T magnetic field,harmonic radiation of ap-proximately 800GHz is measured.By further expanding the magnetic field adjustment range,the funda-mental waves are measured under different TE modes covering a wide frequency range from 217GHz to 381GHz,with power ranging from decades to hundreds of watts.Preliminary experimental results indicate that the developed gyrotron platform exhibits good output capabilities in both fundamental and harmonic operating modes.
