Abstract

In helix traveling-wave tubes (TWTs), average power is being restricted due to thermal management of helix.In increasing requirements of power and wideband miniature size TWTs, thermal issues are becoming rigorous problem.Moreover,if TWTs are to be used for space applications, where size and weight are being restricted, proper thermal analysis is necessary to enhance the life of TWT. In TWTs, the major portion of heat, generated in the helix, is conducted through support rod and some part may be radiated from the uncovered portion by support rods(neglected here) to the metal envelope. Thus the shape, size and property of the support material determine the amount of heat conduction from the helix. In this paper, authors have studied the effect of support rod geometries on heat dissipation from helical slow wave structure in space TWTs.
