並列タイトル等Development of a 300 GHz material processing system
一般注記High power THz-frequency material processing has great potential for the applications. The gyrotron is a microwave tube capable of delivering very high microwave power in the pulse and CW operation at the THz frequencies. The frequency of gyrotron is proportional to the intensity of magnetic field, because the operation results from the mechanism of “cyclotron resonance maser". Therefore, in order to achieve high frequency operation, we need a high magnetic field which superconducting magnets or pulsed-magnets produce. We developed the material heating system by using a 300 GHz gyrotron. This system consists of a 300 GHz, 3.5kW, CW gyrotron (Gyrotron FU CW I) with a cryogen-free 12 T superconducting magnet, a corrugated circular waveguide and an applicator. The distribution of the electromagnetic power in an applicator was measured by IR-camera. Thermal insulators, which were desired small absorption of electromagnetic wave tested by using this system. A focused electromagnetic wave was applied to the melting of the powder of the quartz.
