	The Synchrotron SOLEIL is a large-scale research facility in France that provides synchrotron radiation from terahertz to hard X-rays for various scientific applications. To meet the evolving needs of the scientific community and to remain competitive with other European facilities, SOLEIL has planned an upgrade project called SOLEIL-II. The project aims to reconstruct the storage ring as a Diffraction Limited Storage Ring (DLSR) with a record low emittance which will enable nanometric resolution. The mechanical design of the upgrade project involves several challenges such as the integration of new magnets, vacuum chambers, insertion devices and beamlines in the existing infrastructure, the optimization of the alignment and stability of the components, and the minimization of the downtime during the transition from SOLEIL to SOLEIL-II. The mechanical design is mainly based on extensive simulations, prototyping and testing to ensure the feasibility, reliability, and performance of several key elements. This abstract presents an overview of the mechanical design concepts and solutions adopted for the SOLEIL-II project.

WEPPP058	Permanent Magnets in SOLEIL II	240

	Twenty years after SOLEIL Synchrotron was established, the facility needs to adapt to follow new scientific fields that have emerged since. The proposed new lattice for upgrading SOLEIL storage ring will reduce the horizontal emittance by a factor 50 to reach less than 100 pm.rad. This new lattice presents significant challenges and requires compact magnets that provide strong gradients. As a result, permanent magnet (PM) technology is preferred over electromagnet (EM) technology whenever possible. All sextupoles and octupoles will be EM to ensure efficient optic correction. However, all dipoles, reverse bends and quadrupoles will be PM. The replacement of aging infrastructure and the use of PM will lead to a noticeable reduction in SOLEIL’s electric power consumption and environmental footprint. SOLEIL II lattice consists of 116 dipoles with gradient and 354 PM quadrupoles which can also be used as reverse bends. All PM multipoles have been designed by SOLEIL¿s Mechanical Engineering Group in close collaboration with the Magnetic and Insertion Devices Group. This contribution will present the design, assembly procedure, and prototyping of SOLEIL II PM multipoles.
