Development of 203 GHz band frequency tunable Gyro BWO and its application to the first experiment on accurate measurement of energy difference between two states of positronium under collaboration with International Center for Elementary Particle Physics of University of Tokyo. In order to solve the problem on the difference between theoretical and experimental results of HFS measurement, we have developed a new gyrotron device(Gyrotron FU CW GI) with a Gaussian beam output and made a planning of the experimental set-up for this study.

与东京大学国际基本粒子物理中心合作研制了203 GHz波段频率可调谐陀螺返波管，并将其应用于首次精确测量电子偶素两态能量差的实验。为了解决HFS测量的理论和实验结果之间的差异的问题，我们已经开发了一种新的回旋管装置（Gyrotron FU CW GI）与高斯光束输出，并作出了本研究的实验装置的规划。
