    Línea de transmisión cuasi-óptica con modos gaussianos de orden superior para sistemas basados en gyrotrones tecnológicos para aplicaciones cerámicas

    In this paper, a description of a new compact microwave oven system based on a tecnological gyrotron for material processing applications is presented. The whole system has been designed by the Institute of Applied Physics in Nizhny Novgorod (Russia) and nowadays is installed in the Forschungszentrum (Karlsruhe, Germany). It consists ot a technological gyrotron working at 30 GHz giving 10 Kw CW in the TE02 circular waveguide mode, a quasi-optical transmission line (optimized in this work) and the final very oversized cavity or applicator. The original transmission line had a transmission efficiency of about 70%, by using a Vlasov launcher to generate a fundamental gaussian beam from the TE02 mode. The power was driven through a total of three mirrors. The improved design presented here increases the transmission efficiency up to 91%, by using a higher order gaussian beam mode, azimuthaly polarized and conical profile, by using only two ellipsoidal mirrors.

    Antenas de bocina optimizadas para acoplar modos gaussianos de orden superior

    The concept of higher order free space modes, gaussian-like beam modes can be applied to efficiently transport the power generated by a gyrotron for technological applications. Waveguide modes can be coupled properly to higher order gaussian modes. These modes can be guided by an optimized higher order beam waveguide to the final experiment. A family of optimized non linear horn antennas is investigated in order to maximize the coupling between the guided output modes of a technological gyrotron and the free space modes. The numerical computations show very favourable coupling to higher order gaussian modes, with a conversion effiencies of about 99.8%.
