A design of a sheet-beam electron-optical system (EOS) for a microfabricated $W$ -band traveling-wave tube (TWT) is presented. The proposed TWT is based on a rectangular field-emitter array (FEA) and a planar helix slow-wave structure with straight-edge connections (PH-SEC). The PH-SEC is designed to work with a 5-kV and 10-mA sheet electron beam. The particle-in-cell simulation results show that...
A novel design of a sheet beam electron gun, suitable for a Ka-band microfabricated traveling-wave tube (TWT), is described in this paper. Simulations take into account emission from a CNT field-emitter array (FEA) and the formation of the sheet beam. The rectangular FEA cathode of 2250×300 µm2 area produces a 10 mA sheet electron beam which is compressed into a 350×150 µm2 area. The configuration...
