Design of an Interaction Circuit for a High-Power Multiple-Beam Klystron
摘要
Design of an interaction circuit for a high power, S-band Multiple-beam Klystron (MBK) has been presented in this paper. The interaction circuit consists of a six numbers of coaxial double reentrant cavities operating in TM020 mode. Cold circuit parameters of coaxial reentrant cavities have been computed using microwave studio and RF performance has been obtained through Particle-In-Cell (PIC) simulation. An output power of 15 MW over 4 MHz bandwidth with a power gain of more than 50dB could be achieved through the simulations.
