ABSTRACT
This paper describes a simple method to design a symmetrical pill box window used in high power klystrons. Analytical formulation is cross validated and fine tuned using commercial codes CST Microwave studio and HFSS. These results are finally tested by a fabricated cold test model. Low RF power measurement results of the cold test model agrees quite closely with that of analytical and simulation results. A code has also been written based on these analytical formulae. A parametric study has also been conducted by varying different important design parameters. Optimized thermal simulation is also presented in this paper.
