The ELETTRA storage ring magnets

24 dipole magnets, 108 quadrupoles, 72 sextupoles and 82 steerers are needed in the storage ring. The very stringent requirements for the magnet field quality were met with the use of a combination of 2D and 3D magnetic design. The dipoles are combined function elements with a field index n=13 and a maximum magnetic field of 1.5 T at the central orbit. The curved (R=5.5 m) pole profiles were obtained by matching the stacked laminations. The quadrupoles and sextupoles are made by assembled pole pairs in a C shaped structure with the aperture on the outer side of the ring. To insert the vacuum chamber inside the magnets this structure allows a symmetric opening of the yoke. The steerer magnets provide both horizontal and vertical magnetic fields; an inverted U shape with a 3D optimization of the vertical field coils and positions was studied to provide space for the connection of vacuum pumps
