The amplifier performance is assessed by full-wave and interaction simulation. Properly designed nose cones are shown to enhance the beam-wave coupling. This, in turn, improves the amplifier gain, a weak point of conventional FW-TWTs. The achievable beam efficiency is increased without sacrificing too much bandwidth.enNose-cone loaded folded-waveguide delay lines for Q-band traveling-wave tubesConference Paper10.1109/GEMIC.2016.7461634Conference Paper
