Authors:Christoph Eichhorn; Lukas Pietzonka, Frank Scholze, Carsten Bundesmann, Daniel Spemann, Horst Neumann Hans J. Leiter Abstract: Methods based on laser-induced fluorescence spectroscopy are widely used for spatially resolved non-intrusive diagnostics of atomic or molecular densities and velocity distributions in plasma applications.

Authors:Carsten Bundesmann; Christoph Eichhorn, Horst Neumann, Frank Scholze, Daniel Spemann, Michael Tartz, Hans J. Leiter, Roman Y. Gnizdor Fabrizio Scortecci Abstract: The lifetime of electric propulsion (EP) thrusters depends particularly on the erosion characteristics of operation relevant components, for instance, the grid hole erosion of gridded ion thrusters or the chan...

Authors:Andreas Neumann; Jens Simon Jens Schmidt Abstract: Electric space propulsion thrusters only produce low thrust forces. For the fulfillment of a space mission this implies long thruster runtimes, and this entails long qualification times on ground. For such lon... PubDate: 2021-11-23T00:00:00Z

Wimmer-Schweingruber Abstract: The plasma diagnostics presented in this article target the plasma surrounding a spacecraft that is created by the electric thruster and its surface modifying effects. The diagnostic package includes a retardi... PubDate: 2021-10-27T00:00:00Z
