Design and characterization of RF cavity for a L-band multi beam klystron

摘要

A five beam klystron operating in L band with 2 kW (CW) output power is being designed at CSIR-CEERI for its intended applications in communication. The present paper discusses the design of RF cavity for the klystron. The dimensional parameters of the five beam RF cavity have been calculated initially through standard analytic formulas and then optimized through simulations in CST Microwave studio and MAGIC -3d codes. The cavity has been fabricated and characterized, the measured results are in agreement with the simulation.
