N2 - An ultra-wide band W-Band travelling wave tube using staggered double vane slow wave structure (SDV-SWS) combined with plan alignment three pencil beams is investigated in this paper. Instead of only using the fundamental mode, the first two modes of SDV-SWS are designed to match with the same electron beam to promote the bandwidth. Particle in cell (PIC) simulations with our new type of two stages SDV-TWT predict that when the beam voltage is of 22kV and beam current of 3×0.15A respectively, the travelling wave tube can produce over 2.12 kW of peak power within the total length of 70 mm, also with a corresponding gain of 42.5 dB and an electronic efficiency of 21.4% at 94 GHz. And the 3 dB bandwidth can be achieved about 28 GHz, which is almost the twice high than the one mode SDV-TWT with same parameters before.
