研制了一台28 GHz 500 kW回旋管，用于串列镜伽马10的电子回旋共振加热系统。通过实验优化获得了570 kW的最大输出功率。在300 ~ 500 kW输出功率范围内，尽管受到现有磁体的限制，优化后的回旋管效率仍达到40 ~ 50%。通过调整回旋管线圈参数和对回旋管及磁屏蔽设计的微小改动，使GAMM 10的磁系统漏磁场产生的不良影响降到最低。
A new 28GHz 500kW gyrotron was developed for the electron cyclotron resonance heating system of tandem mirror GAMMA10. The maximum output power of 570 kW was obtained by experimental optimization. The efficiency of the gyrotron is 40˜50% in the power range of 300˜500 kW output with the optimization in spite of the restriction of the present magnet. The non-desirable influences caused by the leakage field of the magnet system of GAMM10 were minimized by the adjustment of gyrotron coi l parameters and the minor change of the gyrotron and magnetic shield design.
