| 摘 要： | 作为目前工作在太赫兹频段输出功率最大的辐射源之一回旋管的功率可达到数十千瓦. 传统太赫兹回旋管一般为点频工作，难以满足动态核极化核磁共振等多方面技术需要。采用机械调节的方式，实现了带宽为2GHz中心频率为0.42THz二次谐波频率连续可调同轴回旋管，通过非线性理论分析发现，在不改变工作磁场条件下，在调节带宽范围内，可实现大于8kW的功率输出.

| Abstract: | As one of the high-power radiating sources in terahertz region, the output power of gyrotrons is up to several tens of kilowatts. The traditional terahertz gyrotrons are difficult to meet the needs of nuclear magnetic resonance using the dynamic nuclear polarization technique, for working in a fixed frequency. in this paper the continuous frequency tunable 0.42THz coaxial gyrotron with 2GHz bandwidth by mechanical tuning has been studied. The results show that the output power can keep over 8 kilowatts level in the tuning bandwidth with unchanged operating magnetic field. |

| Keywords: | frequency continuous tunable Terahertz coaxial gyrotron high power |
