Danfysik A/S, Taastrup, Denmark

Danfysik is currently producing 60 up to 3.3 m long magnet systems consisting of up to 12 multipole magnets integrated into each of the yokes for the bending achromats of the MAX IV 3 GeV storage ring and 12 similar systems for the MAX IV 1.5 GeV storage ring. Each magnet yoke contains combined function soft-end dipole and quadrupole elements which are machined out of one single iron block at tolerances of ± 0.02 mm. In addition, separate, higher order multipole magnets are kinematically mounted into the yokes. The integration of many magnetic elements into single yoke structures enables a compact, low emittance storage ring design. The dipole and quadrupole magnetic elements are magnetically field mapped with high precision on a 3D hall probe measuring bench. Higher order multipoles are measured on a slow rotating coil system developed for that purpose. Much effort has been put into automation in order to quickly perform the very comprehensive measurement program each girder will through.
