Abstract :
A useful design technique of helix pitch profile for high-efficiency Traveling-Wave tubes (TWTs) is put forward. The purpose of the design technique is to increase the normalized axial growth rate of ac electric field amplitude by selecting an appropriate helix pitch profile and so that the power and efficiency are maximized.
