Design and construction of the magnets and insertion devices for the SOLEIL synchrotron

The construction phase of SOLEIL, the French third generation synchrotron radiation source has begun in January 2002 with the aim of starting user operation in spring 2006. The energy of the machine is 2.75 GeV and it consists in a 354 m circumference electron storage ring, with 16 cells and 24 straight sections. The lattice is designed for a good dynamic acceptance even for large energy deviation (up to 6%) and requires very small multipolar components. All the magnets have been computed with 3D model on TOSCA code and the industrial production has started. The paper describes the 32 dipole, 160 quadrupole and 120 sextupole magnets including their interface with the vacuum chamber. Among the proposed ID beam lines, six ID´s of four different types (APPLE 2, long and medium period electromagnetic undulator and in vacuum) have been identified to be ready for the commissioning of SOLEIL. The paper presents their principal characteristics and shows the expected brilliance performances. Two original designs are described to produce any kind of polarization with long period electromagnetic undulators.
