Abstract :
This paper presents results from some of the tools currently used at CPI for design of helix TWTs, coupled-cavity TWTs and klystrons. HFSS, a commercial 3D electromagnetic code, and CTLSS, a 3D electromagnetic code, are currently used to predict helix circuit dispersion and impedance characteristics. CTLSS and HFSS are the first tools available that allow us to perform completely cold-test-free helix TWT design. HFSS is also used to predict CC-TWT circuit dispersion characteristics and to design waveguide transformers, windows and severs.
