Three types of staggered double vane slow wave structure (SDV-SWS) system are put forward including sheet beam, double-mode multi-beam and high-order-mode system, respectively. The sheet beam SDV SWS system, which is a two-stage 42+59 periods structure could get a 275W output power and a corresponding gain of 38dB at 220GHz with a 45GHz bandwidth from 215-260GHz. The double-mode multi-beam wide-band SDV-SWS system using a two-stage 42+48 periods structure, could obtain an over 300W output and a 70GHz ultra-wide band. The TE20high-order-mode SDV-SWS system is a three-stage 31+31+31 periods structure and could get a nearly 53W output power, a 30GHz bandwidth with a nearly 30dB gain, which still has great spaces for improvement. The above research works could promote the development of new ideas and schemes of terahertz high-power and broadband TWT.
