並列タイトル等Development of the material processing system by using the 300 Gyrotron FU CW I
一般注記The effective characteristics of high frequency and strong electric field processing were observed. One of the interesting effects is the so-called non-thermal effect or microwave effect. In order to widely study the non-thermal effect of ceramics sintering and application of material processing, we developed a material processing system by using the 300 GHz gyrotron FU CW I. This system consists of a 300GHz, 2.3 kW, CW gyrotron with a cryogen free 12 T superconducting magnet, a corrugated circular waveguide and an applicator. In submillimeter wave region, the distribution of the electromagnetic wave shows inhomogeneity inside a simple applicator. In order to improve distribution, polygonal reflector was developed and installed into an applicator. By using a polygonal reflector, homogeneity of the electromagnetic wave inside the applicator was improved by three times. In addition, in order to study the non-thermal effect, it is important to study the dependency of the electromagnetic field intensity. In order to control the electromagnetic field intensity independent of the sample temperature, pulsed operation system was developed. A semiconductor switch, by using the power MOSFET, was inserted between a cw power supply and a gyrotron. As a result, variable pulsed operation of a gyrotron was obtained.
