Design and simulation of an S-band compact multi-beam klystron
AIP Advances(2023)
Abstract
The miniaturization and high power of klystron are the main concerns of accelerators. Multi-beam klystron (MBK) can accommodate higher power and a lower operating voltage than single-beam klystrons, significantly reducing volume and weight. This paper introduces the design and simulation of the beam-wave interaction system and multi-beam electron gun for S-band compact MBK. The 3-D particle simulation results show that the output power of the MBK is 12.6 MW, driven by an input signal with a frequency of 2856 MHz and a power of 13 W. The corresponding efficiency is 70%. In addition, the gain of the MBK is 59.9 dB. The design goal of S-band miniaturized high-power MBK is realized.(c) 2023 Author(s).
