THE SOLAR WIND CALIBRATION LABORATORY IN KIEL — •Michael Stalder, Christian Seigies, and Robert Wimmer-Schweingruber — Leibnizstrasse 11, 24118 Kiel
A new ECR ion source (ECRIS) using permanent magnets only has been developed for the use in a solar wind calibration laboratory at the University of Kiel. The main goal of the new ECRIS is to produce highly charged ions such as Fe20+ to simulate the solar wind. The ECRIS and an 90o sector magnet are placed on a high voltage platform, allowing the static acceleration of ions in the energy rage of 1keV/q .. 450keV/q. We designed an all permanent magnet system using additional iron rings to shape the magnetic field. A plateau in the axial magnetic field strength Bz leads to a big resonance volume. The form of the Bz field plateau can be adjusted by moving the iron rings in the axial direction. Changing the iron rings leads to resonance frequencies in the range of 10GHz to 14GHz. Our magnet design leads to a simple magnet geometry and a high axial mirror field strength of BzMax = 1T. The main components for the new solar wind laboratory in Kiel are built and assembled. The laboratory will be ready to use at the end of 2005.
