چکیده
|
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. © 2017,the author(s).
