项目摘要

In this project, we have developed frequency-tunable, medium power, submillimeter wave gyrotrons an applied them to submillimeter wave spectroscopy. In the process, the collaboration between Fukui University and University of Sydney playd an important and fundamental roles.1) Ultra-high frequency operation of gyrotron by the second and the third harmonics Using 12T and 17T superconducting magnets, we developed high frequency gyrotrons whose frequencies are close to 1 Terahertz. We have achieved the highest frequency of 847 GHz. This frequency is the world record of high frequency operation of gyrotron.2) cw operation of gyrotronWe have realized complete cw operation of the gyrotron and succeeded to achieve stabilities of amplitude and frequency of the gyrotron output, in order to apply the gyrotron to submillimeter wave spectroscopy as radiation source.3) Amplitude and frequency modulations of the submillimeter wave gyrotron outputWe have achived amplitude and frequency modulations of the gyrotron output for its application to wider fields.4) Studies on mode competition and mode cooperation between the fundamental and the second harmonic operations5) Development of quasi-optical transmission system for submillimeter wave gyrotrons outputs6) Development of a high sensitive detector in a millimeter wave range using a high T_c superconductor7) Plasma scattering measurement using a submillimeter wave gyrotron as a radiation sourceWe have applied the submillimeter wave scattering measurement system using our gyrotron (GYROTRON FU II) as a radiation source for CHS in National Institute for Fusion Science and succeeded in measurement of drift wave excited spontaneously in the device.8) Study on the millimeterr wave ESR using a gyrotron as a radiation source

在这个项目中，我们开发了频率可调的中等功率，亚毫米波旋转，并将其应用于亚毫升波光谱。在此过程中，福岛大学与悉尼大学之间的合作是重要而基本的角色。1）使用12T和17T超导磁铁的第二和第三个谐波对陀螺的超高频率操作，我们开发了高频陀螺仪，其高频陀螺仪的频率高频率接近1 Terahertz。我们达到了847 GHz的最高频率。该频率是循环负数高频操作的世界记录。2）Gyrotronwe的CW操作已经实现了Gyrotron的完全CW操作，并成功地实现了陀螺仪输出的振幅和频率的稳定性，以便将旋转子应用于亚毫米波波光谱法作为辐射来源。3）亚毫米波循环的幅度和频率调制我们已经实现了陀螺仪输出的幅度和频率调制，以应用于更广泛的领域。4）研究模式竞争与模式合作的研究操作5）使用高t_c超导体的高敏感探测器在毫米波范围内开发高敏感探测器的高光电传输系统的开发。使用我们的Gyrotron（Gyrotron Fu II）作为CHS的辐射源的测量系统在国家融合科学研究所的辐射源，并成功地测量了设备中的漂移波的测量。8）研究使用陀螺仪作为辐射源对毫米级波ESR进行研究
