“…Telstar satellites were nearly spherical polyhedra of 88 centimetres diameter for 77 kilograms. They were composed of the new technology required for satellite communication, like thousands of transistors for other various electric systems, solar cells for power generation, and a 4 GHz helix traveling-wave tube amplifier from Bell Labs [Bodmer 1963]. In fact, all the satellite's active elements were solid-state devices (transistors) excepted for the TWT amplifier.…”

equipe turbulence plasma, case 322 campus Saint Jérôme, av. esc. Normandie-Niemen,The traveling-wave tube is a critical subsystem for satellite data transmission. Its role in the history of wireless communications and in the space conquest is significant, but largely ignored, even though the device remains widely used nowadays. This paper present, albeit non-exhaustively, circumstances and contexts that led to its invention, and its part in the worldwide (in particular in Europe) expansion of TV broadcasting via microwave radiorelays and satellites. We also discuss its actual contribution to space applications and its conception. The originality of this paper comes from the wide period covered (from first slow-wave structures in 1889 to present space projects) and from connection points made between this device and commercial exploitations. The appendix deals with an intuitive pedagogical description of the wave-particle interaction.

“…Space travelling-wave tube (TWT) forms an integral part of microwave amplification system in most communication satellite transponder [1]. In a typical Ku-band space TWT, 30% of the consumed power is wasted as heat, most of which is in the collector region [2].…”

Thermal Impact on the Performance of Highly Efficient Multi-stage Depressed Collector for Space TWT

et al. 2014

In a travelling wave tube, much of the waste power is dumped into the collector. If the waste heat is not properly managed, it might pose a serious problem causing even failure of tube. In this paper, the optimal choice of thermal management of a highly efficient multistage depressed collector designed for a space TWT has been made based on several criteria. The structural deformations and stresses developed due to thermal impact have been evaluated. The influence of thermal deformations on the collector electrical performance and high voltage withstanding capability has been studied during hot condition.

The Telstar spacecraft design is discussed with emphasis on the electronics system. The description includes early planning, starting with frequency allocation considerations, and carries the program through electrical and mechanical design, construction and evaluation of the electronics system. The content is aimed at a broad introduction, depending on companion papers for many details of the spacecraft design.
