高出力遠赤外光源(ジャイロトロン)の開発と遠赤外新技術

High frequency, high power, high harmonic gyrotrons which cover a wide frequency range in millimeter and submillimeter wavelength region are being developed as far-infrared radiation sources and applied for new far-infrared technologies, for example, plasma diagnostics, electron spin resonance (ESR) spectroscopy and so on. The present status of the development and applications of the high frequency gyrotrons are summarized.
