摘要

根据30W级w波段折叠波导连续波行波管(TWT)的原始设计，在均匀相互作用电路的末端采用阶梯锥形结构来提高电子效率。对比两种锥形电路，结果表明两种电路在91GHz~97GHz频段均能达到40W以上的功率。电子效率可从3%提高到4%。得到了进一步提高总效率的集热器设计，仿真结果表明，最高总效率为23.6%。

Design optimization of W-band CW TWT for improving overall efficiency

According to the original design of 30W level W-band folded waveguide CW traveling wave tube (TWT), a step-tapering structure was at the end of the uniform interaction circuit to improve the electron efficiency. Compared two kinds of tapering circuit, the results indicate that both circuits could achieve over 40W power at 91GHz~97GHz. The electron efficiency could be improved from 3% to 4%. A collector design is obtained to improve overall efficiency further, and simulation shows top overall efficiency is 23.6%.
