Abstract

Many methods, for example, coating attenuation materials in a open cavity, making some slots along longitudinal or azimuthal direction on the cavity wall, or using some complex cavities, have been used for increasing the mode selectivity, improving the stability of operating mode and enhancing the output power and interaction efficiency in gyrotron applications. In this paper, a new type of complex cavity structure is used to improve the selectivity of modes. The resonant characteristics of the cavity as well as the effects of thickening the mutual wall and constructing a drift tube in it on the operating mode stability are numerically analyzed and adjusted with Ansoft HFSS code. The cavity has been designed and tested
