Abstract

ANKA is a 2.5 GeV storage ring under construction. The storage ring consists of 16 bending magnets with a maximum field of 1.5 T, 40 quadrupoles divided in five families with a maximum gradient of 20 T/m, 24 sextupoles with a maximum second order differential of 550 T/m², and 44 correctors with a maximum kick capability of 0.8 mrad. The production of all the magnets is now finished and the magnets have been mechanically and magnetically characterized to ascertain their excitation curves and field uniformity. For the dipoles a Hall probe has been used to map the magnetic field while for the quadrupoles and sextupoles a rotating coil system has been used to determine the magnitude of the high order multipoles. In this paper the analysis of these data is discussed and results for measured magnets are presented
