High-efficiency klystrons are the need of the hour, as they are essential to meet the demands for high-power applications. High-efficiency klystrons use multiple beams and extended interaction cavities. An 8-beam extended interaction intermediate cavity with high R/Q has been designed for the application of a high-efficiency klystron in the C-band. The 8-beam input cavity and extended interaction output cavity with slot coupling have also been represented. Special attention has also been given to the design so that the gap of each of the 8 beamlets has equal coupling. External quality factors of both the input and output cavities have also been optimized. Parametric analysis of the external quality factor with respect to the dimensions of the coupling slot has been investigated to get an idea of suitable dimensions for high-efficiency output. All simulations have been done using CST Microwave suite.

摘要

High-efficiency klystrons are the need of the hour, as they are essential to meet the demands for high-power applications. High-efficiency klystrons use multiple beams and extended interaction cavities. An 8-beam extended interaction intermediate cavity with high R/Q has been designed for the application of a high-efficiency klystron in the C-band. The 8-beam input cavity and extended interaction output cavity with slot coupling have also been represented. Special attention has also been given to the design so that the gap of each of the 8 beamlets has equal coupling. External quality factors of both the input and output cavities have also been optimized. Parametric analysis of the external quality factor with respect to the dimensions of the coupling slot has been investigated to get an idea of suitable dimensions for high-efficiency output. All simulations have been done using CST Microwave suite.
