Abstract :
This paper presents the results from a numerical code based on a full-wave finite element analysis developed to solve the helix problem used as a slow-wave-structure in a typical TWT to operate in X-band. The three dimensional code has been used to produce accurate cold-test features including frequency dispersion, helix impedance and slab dielectric helix support effects.
