介绍了一种使用20 T超导磁体进行二次谐波工作的连续波1太赫兹回旋管的设计。采用模式竞争分析方法研究了在920 GHz ~ 1014 GHz频率范围内激励的二次谐波模式的工作条件。使用加速电压为30 kV、电流为200 mA的电子束，可获得高达250瓦的输出功率，效率为4.16%。该回旋管的重要优点是即使在大电流下也能保持二次谐波的单模激发和极高的辐射频率。这为实现1太赫兹高功率辐射源提供了可能。这种回旋加速器正在福井大学的FIR中心建造。
Design of a CW 1 THz gyrotron at second harmonic operation using a 20 T superconducting magnet has been described. The mode competition analysis is employed to investigate operation conditions of second harmonic mode, which is being excited at the frequency ranging from 920 GHz to 1014 GHz. The output power up to 250 watt corresponding to the efficiency of 4.16 percent could be achieved by using an electron beam with accelerating voltage 30 kV and current 200 mA. The important advantage of this gyrotron is that the single mode excitation at second harmonic, and extremely high frequency of the radiation, could be maintained even at high currents. It opens possibility to realize a high power radiation source at 1 THz. Such gyrotron is under construction at FIR Center, University of Fukui.
