二次谐波回旋加速器FU CW GII和Gyrotron FU CW GIII是日本福井大学远红外区域发展研究中心为实现两个目标而开发的。每个回旋管都配备了一个内部准光学模式转换器。使用Gyrotron FU CW GII可以验证腔和模式转换器的设计，这是第一个目标。之后，Gyrotron FU CW GIII是Gyrotron FU CW GII的改进版本，使我们能够实现高达420 W的高功率输出，这是第二个目标，阴极电压设置为- 21 kV，束流电流为0.57 a。这是用一种新开发的电子枪和小心地把回旋管放在磁铁上实现的。
Second harmonic gyrotrons, Gyrotron FU CW GII and Gyrotron FU CW GIII, were developed at the Research Center for Development of Far-Infrared Region, University of Fukui, Japan to achieve two goals. Each gyrotron was equipped with an internal quasi-optical mode converter. Using Gyrotron FU CW GII allowed the design of the cavity and mode converter to be validated, which was the first goal. After that, Gyrotron FU CW GIII, which is an improved version of Gyrotron FU CW GII, allowed us to achieve a high power output of up to 420 W, which was the second goal, with a cathode voltage setting of −21 kV and a beam current of 0.57 A. This was achieved using a newly developed electron gun and with the careful sitting of the gyrotron on the magnet.
