Abstract

Abstract

In order to meet the diagnosis requirements of asymmetric mode competition in an X-band triaxial klystron amplifier, a novel waveguide coupler with compact structure is designed, and its coupling characteristics for TE61 mode are analyzed with small-hole coupling principle and CST simulation software. A physical model is established by using PIC method to diagnose the spectrum characteristics in the TKA coaxial drift tube. Through simulation, the validity of the designed coupler to diagnose TKA asymmetric mode competition is verified.
