Disponível em: http://repositorio.ipen.br/handle/123456789/16062.http://repositorio.ipen.br/handle/123456789/16062The construction and the characterization of a multi-sections solenoid to be used as a magnetic focusing structure of a TWT is reported in this paper. Using copper sheet as electric conductor, the developed solenoid is able to produce a magnetic density flux of 175 mT on axis with 10 A and electrical power of 2.2 kW. Electrical, magnetic and thermal characterizations of the device are presented. Comparison between theoretical and experimental results are shown and discussed.224-226openAccesstravelling wave tubesmagnetic fieldselectron beamssolenoidsfocusingTexto completo de evento10.1109/IMOC.2005.1579983
