Outline of Final Research Achievements

One of the effective way of heating the fusion plasma is the injection of the high frequency electromagnetic wave (so called millimeter wave which the wavelength is millimeter range). Such a high power millimeter wave can be generated by the gyrotron. This study is the development of the mode convertor and built-in mirrors for the gyrotron. The gyrotron is usually designed for single frequency generation, but if the gyrotron can generate the alternative frequency, it can expand the range of heating position (the heating position depends on the frequency). The development of these components were successfully finished.
