The development of an X-Band triaxial input system for the high-power gyroklystron amplifier experiment at the University of Maryland, College Park, is proposed and discussed. In order to obtain high mode purity of a TE[sub 011] mode in an overmoded coaxial input cavity while maintaining high coupling efficiency, a coaxial dual-cavity input structure with an outer TE[sub 411] mode and an inner TE[sub 011] mode coaxial cavity has been designed to obtain a low Q and to avoid mode distortion due to the coupling aperture between the input waveguide and the input cavity. A loaded quality factor of 73 and a resonant frequency of 8.570 GHz with high mode purity have been obtained for the inner TE[sub 011] mode coaxial cavity. The experimental results are in good agreement with the theoretical designs. The details of the design methods and cold-test results of the X-Band triaxial input system are presented in this paper.
