Abstract :
An increase in the frequency of microwave used for the processing of materials has a great potential for the applications. We developed the material heating system by using a 300GHz gyrotron. This system are consisted of a 300 GHz, 3.5 kW, CW gyrotron with a cryogen free 12 T superconducting magnet, a corrugated circular waveguide and an applicator. The circular corrugated waveguide (i.d. = 6.35cm) with a corrugated period and depth of 254 μm have been designed. The applicator have been designed both volumetric heating by uniformly distributed microwave and surface heating by a focused wave beam.
