三个兆瓦级77GHz回旋管已用于铲运机ECRH系统。它们的操作可以通过阳极电压的两步上升而高度优化。第三回旋管获得了1.78MW的输出功率和37.9%的效率。推进了系统的改进，包括毫米波束流位置和轮廓监测器的研制。
Three Mega-Watt 77GHz gyrotrons were developed for an ECRH system in LHD. Their operation could be highly optimized by means of two-step rise of an anode voltage. Output power of 1.78MW with 37.9% efficiency were obtained in the 3rd gyrotron. The system improvement has been promoted including the development of a mmw-beam position and profile monitor.
