Abstract
In this paper, the new slow-wave structure called wave-ring helix to enhance the power of the traveling wave tubes is introduced. In this new structure, without increasing the length and radius of the helix, the wave
motion path can be increased to radiofrequency wave in
phase with the electron beam. The results show that in the
special frequency range the output power and gain are
greater than conventional helix. In this paper, optimization
results are presented in cold and hot tests on the new
structure. The software CST is used in S-band frequency
range.
