P1–5: Development of a 300W peak power J-band klystron

Klystron is vacuum electron device operating in microwave range of frequencies. It is used as power amplifier in a variety of systems including radars, particle accelerators and thermonuclear reactors. With the availability of very reliable design codes, it is now possible to optimize the design and develop a tube with minimum iterations in fabrication. In the present case standard design codes like EGUN, CST Microwave Studio, AJDISK and MAGIC have been used to estimate and optimize different design parameters of klystron for desired tube performance. The paper presents the results of simulation and cold testing.
