It is found that asymmetric beams can significantly increase the body current and the sensitivity to BWO.backward wave oscillationsbeam opticsHelix TWTsimulationImpact of Asymmetric Beam Shapes on the Body Current and BWO Margin in Helix TWTsConference Paper10.1109/IVEC53421.2022.10292342Conference Paper
