  SOLEIL is a third generation synchrotron radiation source, under construction in France near Paris. The storage ring consists of a 357 m circumference ring, with 16 cells and 24 straight sections, out of which up to 21 will house insertion devices (ID). The optics features a low 3.7 nm.rad emittance at the 2.75 GeV operating energy, so as to provide high brilliance, from the VUV up to the hard x-ray domain. To reach a long lifetime, and beam position stabilities in the micron range, significant attention was paid at each design stage (optics, magnets, beam position monitors, vacuum and RF systems…), including on the design of the building, the construction of which is now complete. This resulted in some unprecedented approaches such as the intensive use of NEG coating vessels, or the development of a dedicated SC RF cavity and of 200 kW solid state RF amplifiers. The injector system (100 MeV Linac) and the 3 Hz full energy booster synchrotron have reached nominal operating conditions by fall 2005, while the ring commissioning should start by April 2006. Innovative ID's were designed and built so as to provide the best possible performances in a wide energy range (5 eV to 50 keV).

  The Booster of SOLEIL needs injection and extraction kicker systems with fast transition times, good flat top and low jitter, to allow a satisfactory injection efficiency of the Storage Ring injection. So all the kicker systems have been optimised, to fulfil specifications and to permit the use of solid state switching electronics. This contribution presents the ceramic vacuum chambers and magnets design, the specific pulse forming scheme and the realisation of the pulsed power supplies working up to 20 kV. Electrical and magnetic measurements results of kickers systems are given, and also its operation status from the first SOLEIL Booster injection in July 2005.

  The Top Up injection mode of the SOLEIL Storage Ring needs a very good matching of the four kicker magnet fields. But their implantation inside the straight section dedicated to SR injection imposed high level forces on each of the four kickers. This contribution describes the ceramic vacuum chambers and magnets design optimised to provide a very good identity of the four magnets. The pulsed power supplies, based on IGBT high voltage modules, designed to work at high current (5250 A-9000 V) could be located outside the SR tunnel. We highlight the specific development on all components specification and electrical scheme that permits to reach such a challenge. The electrical and magnetic measurement results are reported.

  The SOLEIL storage ring injection section integrates four matched injection kicker magnets, two diagnostics kicker magnets and a beam shaker, which need ceramic vacuum chambers with an inner titanium coating. For each utilisation (according with its field amplitude and its time or frequency domain), the coating thickness has been evaluated from the different points of view: field attenuation, beam deposited power, magnet excitation deposited power, and cooling efficiency. So we could determine the different coating thicknesses and tolerances needed according to the different magnetic field shapes. The realised ceramic chambers have adequate coating resistances, with in particular a low non-uniformity among the matched injection kicker magnets chambers.

  The commissioning of SOLEIL's storage ring will start in April 2006. The objective is to reach, within a first phase of two months, stable beam conditions at 100 mA in the multi-bunch mode that can be used for the commissioning of the beamlines. This is a challenging objective, especially because the SOLEIL's ring is incorporating some innovative techniques such as the use of a superconducting RF cavity, NEG coating for all straight parts of the machine and new BPM electronics. Prior to the start of the commissioning, some insertion devices and most of the insertion devices low gap vacuum vessels, including 10 mm inner vertical aperture vessels for the Apple-II type, will be installed on the ring. This paper will review the performances of all these equipment in presence of the beam. The results of the first commissioning runs will be presented.
