TRAVELING WAVE TUBE AND ITS MANUFACTURING PROCESS Russian patent published in 1996 - IPC

FIELD: microwave devices. SUBSTANCE: thermal contact between insulating supports 4 and heat-transfer wedges 2 is ensured during tube manufacture along entire length of device. Coolant channels 7 are arranged beyond periodic focusing magnetic system which makes it possible to enlarged as much as desired sectional area of channels 7 and to improved heat transfer from system. Heat transfer from slow-wave system can be also increased when assembling the tube according to method given in formula to be found in description of invention. method involves thermal compression of high-frequency stack along entire length of traveling-wave tube to improved thermal contact and heat transfer from slow-wave system. EFFECT: improved power capacity and reliability of tube.
