Development of a position-sensitive Faraday cup array beam diagnostic for the solar wind laboratory at the University of Kiel — •Lauri Panitzsch, Michael Stalder, Robert Wimmer-Schweingruber, Christiane Helmke, Christian Steigies, Onno Kortmann, Stephan Böttcher, Oliver Rother, Stefan Kolbe, Lars Seimetz, and Horst Schlüter — IEAP, University of Kiel, Germany

The department of extraterrestrial physics of the university of Kiel is establishing a solar wind laboratory which will be used mainly for three purposes: calibration of space instruments interacting with the solar wind, research on space weathering of dust particles, and for fundamental plasma physics. The laboratory will be able to generate a well defined highly-charged ion flux, similar to the solar wind, at energies from 1- 450keV/q. To generate this flux, ions of different charge states are produced in a 10-14GHz Electron-Cyclotron-Resonance Ion Source (ECRIS).

Both, calibration and dust particle bombardment, need accurate values for the main beam parameters such as current, position and profile. While the current will be measured by a single Faraday Cup (FC), position and profile of the ion beam will be acquired with a Faraday Cup Array (FCA) which can be moved through the beam. This array will allow high resolution, accuracy and durability even for the expected current range (pA → mA) and a beam power up to 40W.

Here, we report on the design, assembly, implementation, and testing of the FCA.
