Theoretical Description and Numerical Calculations of significant three-dimensional Magnetic Field Configurations — •Anna Mierau1, Pierre Schnizer2, Egbert Fischer2, Pavel Akishin3, and Thomas Weiland11Technische Universität Darmstadt, Institut für Theorie Elektromagnetischer Felder (TEMF), Schlossgartenstrasse 8, D-64289 Darmstadt, Germany — 2GSI Helmholzzentrum für Schwerionenforschung GmbH, Planckstraße 1, D-64291 Darmstadt, Germany — 3JINR, Joliot-Curie 6, 141980 Dubna, Moscow region, Russia

The heavy ion synchrotron SIS100, the core component of the Facility of Antiproton and Ion Research will accelerate high current ion beams of up to U27+.

For operating such a machine the static and transient magnetic field quality must be fully understood. This is also necessary to keep the beam losses well below acceptable limits and to prepare a sound strategy for high resolution magnetic measurements and data analysis. Challenging preconditions to perform such work are to find a proper description for the non. Cartesian symmetry of the magnets, most important for curved dipoles with elliptical apertures.

We describe the parameterisation methods using elliptic and toroidal multipoles and summarise comparing the calculated to the measured field quality.
