Abstract :
This paper mainly introduces the study for 140 GHz folded waveguide (FWG) traveling wave tube (TWT) with big electron tunnel. Through the high frequency simulation software and 3-D particle in cell (PIC) simulation, we get the structural parameters. By using these parameters, we fabricate the whole vacuum electron device (VED), including the slow wave structure, magnetic focusing system, input and output coupler and so on.
