Design of RF interaction structure for a 352.2 MHz, 100 kW (CW) power klystron

A 352.2 MHz klystron with an output power of 100 kw (CW) is under development at CSIR-CEERI for charged particle accelerator application. A study for the design of RF interaction structure of this klystron has been carried out to get the optimized design parameters. Initially 1-D code AJDISK has been used to predict the interaction parameters of RF structure which is optimized using MAGIC(2D/3D), to get the desired performance of the device. CST Microwave Studio has been used for design of input and output coupler. The paper shall present various simulation results of beam wave interaction.
