Abstract Compact magnet systems for ultra-low emittance synchrotron light sources have been developed at MAXLab*. Results of the production and test at Danfysik of 60 magnet systems for the MAXIV 3 GeV storage ring will be presented. These systems, contain a combined function dipole and up to 12 discrete multipoles integrated into up to 3.3 m long yokes. The production concept and test system has been reported** so here we focus on long term stability and trends of the magnetic performance of individual magnets. A complete series of 12 magnet girders for both the MAXIV 1.5 GeV and the SOLARIS storage rings are also to be produced at Danfysik. With two combined function dipoles and 11 multipole magnets integrated into 4.5 m long iron yokes these magnet systems are significantly larger. The ±0.02 mm mechanical tolerance requirement is a significant challenge but is possible with special attention to the minimization of tolerance build-up effects on the inserted multipole magnets by functional machining. New aspects of the magnetic test concept resulting from multipoles placed deep inside the girder structure will be described together with results from test of the first prototype unit.
