Travelling Wave Tubes (TWT) and klystrons respectively are two of the most important components for communication and earth research spacecraft. Actual requirements have led to TWT's with a heat dissipation up to 600 W (≃ 350 W RF).High dissipating tubes possess usually a selfradiating collector, which does not allow to locate the amplifiers within the payload module. With respect to the requirements of a typical communication S/C TWT with a total dissipation energy of about 500 W, a completely conduction cooled system with heatpipes was developed and tested. The amplifiers can thus be located within the payload module, the heat-pipes being connected to the S/C radiator panel.
