项目摘要

(1) Development of fundamental technologies In for-Infrared regionI) Under cooperation between both institutions, small power, cw gyrotrons are developed. Stabilities and modulations of amplitude and frequency are also realized. II) High sensitive detectors with low noise in millimeter to submillimeter wavelength range are developed using high temperature superconductors (YBCO-BiO). III) A quasi optical transmission system for mode conversion from gyrotron output mode to Gaussian mode is developed and applied for effective uses of the gyrotrons to many objectives.(2) Scattering measurement of helical device LHD (National Institute for Fusion Science)Under cooperation with National Institute for Fusion Science, a submillimeter wave scattering measurement device is prepared for measurement of low frequency density fluctuation in LHD. On the other hand, a quasi optical gyrotron for plasma diagnostics is constructed.(3) Study on submillimeter wave ESRSubmillimeter wave spectrometer using a gyrotron and a high field pulse magnet is constructed. It is used for studies on materials with large zero split and nonlinear phenomenon in ESR. Study on ESR measurement of Fe-SiOィイD22ィエD2 is carried out by using submillimeter wave gyrotron.(4) Sintering of high quality ceramic using a submillimeter wave gyrotronCeramic sintering device using a cw submillimeter wave gyrotron is prepared. It will be used for development of high quality ceramic under cooperation with industry.(5) Application of a submillimeter wave gyrotron to new technology in medicineA catheter which transmits with low loss and heats local small area is developed for its application to new technology in medicine(6) Developmental researches in far-Infrared region up to the present and their future plan are summarized.Contributions of Fukui University and University of Sydney to studies in far-infrared region development are also discissed.
