	The 2.75 GeV synchrotron light source SOLEIL delivers photons to 27 beamlines; 2 new ones are under construction together with the FEMTOSLICING project of which commissioning started in January 2014. Five filling patterns are available for the users in Top-up injection mode. The storage ring is running with an upgraded optics less sensitive to insertion device (ID) configurations and giving both better beam lifetime and injection efficiency. The beam position stability remains excellent with a focus on electron vertical beam-size stability for the new very long beamlines. A gating system during Top-up injection improves significantly the quality of the spectrum on an infrared beamline. Several heavy actions of maintenance and upgrades on crucial subsystem equipment are underway. Others accelerator projects are going on such as the design and construction of new IDs, new Multipole Injection Kicker, radiation damage studies as well as R&D on solid-state amplifiers.

MOPRO053	Study of Upgrade Scenarios for the SOLEIL Storage Ring	203
	R. Nagaoka, P. Brunelle, X.N. Gavaldà, A. Loulergue, A. Nadji, L.S. Nadolski, M.-A. Tordeux SOLEIL, Gif-sur-Yvette, France
	Within the scope of a future major upgrade of the SOLEIL storage ring, presently having the energy of 2.75 GeV, the circumference of 354 m and the horizontal emittance of 3.7 nm.rad, towards a Diffraction Limited Storage Ring (DLSR), the present paper presents and discusses the outcomes of a series of studies launched to explore different possible scenarios for the magnet lattice arrangement, under the constraint of making the upgrade in the same existing machine tunnel. Two scenarios were presented earlier in this context, which both preserved all the existing free straight sections for insertions, though the bending magnet positions were not strictly conserved. The purpose of the extended studies is to explore, in particular, the range of horizontal emittance that can be reached by hypothetically removing some of the existing geometric constraints, such as suppressing or shortening partially the straight sections. The emittance range is equally studied by fulfilling rigorously all constraints. The dependence of the nonlinear properties of the magnet lattice on the linear optics is simultaneously investigated.

	The W164 out-vacuum wiggler was designed and built at SOLEIL with the double goal of producing high energy photons for the PUMA beamline (10 keV to 70 keV) and to be used as a modulator for the FEMTOSLICING project. The insertion device requires simultaneously reaching low resonant energy (1.55 eV) and high critical energy of photons (above 10 keV), leading to the choice of high field and large periods. The 3.28 m long wiggler is composed of 20 periods of 164 mm made of NdFeB magnets and vanadium permendur poles. The required effective field for the FEMTOSLICING is 1.53 T and the maximum total field reaches 1.8T at the minimum gap of 14.5 mm. The small transverse size of the poles was optimized to minimize the magnetic forces (8 tons maximum) resulting, together with the large field produced at minimum gap, to a large vertical dynamic field integral (DFI) inside the horizontal physical aperture of the chamber. A dedicated permanent magnet system was designed, constructed and installed at both wiggler ends to cancel the DFI at minimum gap. The construction of the wiggler, the results of the magnetic measurements and the effects on dynamics measured on electron beam are presented.

Within the scope of a future major upgrade of the SOLEIL storage ring, presently having the energy of 2.75 GeV, the circumference of 354 m and the horizontal emittance of 3.7 nm.rad, towards a Diffraction Limited Storage Ring (DLSR), the present paper presents and discusses the outcomes of a series of studies launched to explore different possible scenarios for the magnet lattice arrangement, under the constraint of making the upgrade in the same existing machine tunnel.
