针对高频回旋管在高功率太赫兹技术中的应用，FIR FU正在开发回旋管FU CW系列。回旋管 FU CW CI 是作为该系列中的亚太赫兹回旋管之一而开发的。陀螺管的优点是结构紧凑，采用紧凑的超导磁体和紧凑的供电系统，使得陀螺管更容易接入大型应用设备，将陀螺管的应用扩展到更广泛的领域。设计的频率和腔模式为394.5 GHz和TE26模式，适用于600 MHz DNP-NMR波谱。运行结果显示，频率为394.03 GHz，输出功率为30 W左右，可应用于600 MHz DNP-NMR测量。此外，该陀螺仪可以在许多其他频率和腔模式下工作，适用于广泛领域的高功率太赫兹技术。本文介绍了包括长脉冲或CW模式的设计和运行结果。
For application of high frequency gyrotron to high power THz technology, Gyrotron FU CW series is being developed in FIR FU. Gyrotron FU CW CI is developed as one of sub-THz gyrotrons included in the series. The advantage of the gyrotron is compactness using a compact superconducting magnet and compact power supply system, which makes the accesses of the gyrotron to applied large-scale devices easier and extends the applications of gyrotron to wider fields. The designed frequency and cavity mode are 394.5 GHz and TE26 mode for application to the 600 MHz DNP-NMR spectroscopy. As the operation results, the frequency and the output power were 394.03 GHz and around 30 W, respectively, which are available for the application to the 600 MHz DNP-NMR measurement. In addition, this gyrotron can operate at many other frequencies and cavity modes for application to high power THz technologies in wide fields. In this paper, the design and the operation results including long pulse or CW mode are presented.
