Related to an electric propulsion system capable of spiraling a satellite from a parking orbit into the synchronous orbit, the ion-thruster ESKA-18-P has been designed for an electric input power of about 700w and an exhaust velocity of 38 km/sec. The characteristic data of this mercury thruster are presented as function of the magnetic field and different mass flow ratios. In addition, some experimental results on hollow cathodes obtained in separate investigations, and beam diagnostic measurements with a multiple Faraday-probe, are reported. Finally, the application of the thruster for a solar electric propulsion module of 2.5 kw is demonstrated. (Author)
