TEMPERATURE DISTRIBUTING OF HELICAL TRAVELING WAVE TUBE SLOW-WAVE STRUCTURE WITH DIFFERENT SUPPORT ROD MATERIAL AND SHAPE

This paper relates to temperature distributing of helical traveling wave tube slow-wave structure with different support rod material and shape by ANSYS.The optimum scheme that the slow-wave structure has fine capability to conduct caloric and is lasted lower temperature to work stably is putted forward,through the compare of different simulation result,the author thinks over hereinafter instances:different support rod material、shape and if having contact thermal resistance among the contact surface.
