Abstract: The focusing and transmission of a sheet electron beam with periodic cusped magnetic (PCM) fields were studied for the terahertz traveling-wave tubes (TWT). Due to the limitation on the ...
Abstract: In order to improve the periodic permanent magnetic (PPM) focusing the performance of traveling wave tubes (TWTs) for the higher current, the analysis and experimental study of the ...
