Development of a beam deflector for the Kiel solar wind laboratory — •Jan Kristoffer Appel, Lauri Panitzsch, Thies Peleikis, Jan Steinhagen, and Robert Wimmer- Schweingruber — Institut für Experimentelle und Angewandte Physik, Christian- Albrechts- Universität, Kiel

The Kiel solar wind laboratory will be used for calibrating space flight instrumentation for solar wind studies and for studying solar wind interaction with matter, e.g. regolith. For that purpose, two different target vacuum chambers are needed to allow testing flight hardware in space conditions and still allow for relatively dusty matter interaction experiments. To switch the ion beam between the two vacuum chambers, an electrostatic beam deflector is needed. A method for simulating ion trajectories inside such a deflector is presented and some simulation results are shown. From these results, the properties and construction of the final deflector design are derived and presented. In order to later quickly assess the beam properties to be expected, the transfer matrix of the deflector can be used. A method for deriving the transfer matrix from simulation data is shown and the predicted beam properties are compared to simulation results.
