The Kiel suprathermal ion calibration facility - current status and next steps — •Lauri Panitzsch, Michael Stalder, and Robert F. Wimmer-Schweingruber — IEAP, Christian-Albrechts-Universitaet zu Kiel, Germany

The University of Kiel is establishing a suprathermal ion calibration facility. One of the main purposes of this facility is the calibration of space instrumentation for the solar wind and suprathermal particles, especially on Solar Orbiter and Solar Probe. The heart of the Kiel facility is a tunable 11 GHz (9-14 GHz) Electron-Cyclotron-Resonance-Ion-Source (ECRIS). A 90°-sector magnet selects the m/q ratio of the ion-beam, before the ions are electrostatically accelerated to energies up to 450keV/q, which equals energies of suprathermal solar particles. Other important beam parameters (beside the m/q-ratio and the energy) are beam current and profile, which are measured with a Faraday Cup (FC) and with a FC-Array respectively, allowing high resolution in current and position measurement. We are currently optimizing the source to increase beam current and the highest achievable charge states. Here we report on the current status of the facilities and the plans for the immediate future.
