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.
