The 2.75 GeV storage ring of the SOLEIL third generation light source in France consists of 16 cells and 24 straight sections (4x12m,12x7m, 8x3.6m) for a total circumference of 357 m. 24 insertion devices are planned for providing high brillance radiation from UV to hard X ray. They consist of adjustable polarisation sources in the UV-soft X ray (electromagnetic devices of periods 640 mm and 256 mm, APPLE-II of periods ranging between 80 and 34 mm, and one EMPHU) and planar devices for the production of hard X ray (in vacuum undulators of period 20 or 26 mm and one in vacuum wiggler). During the commissioning of the presently installed seven insertion devices (HU640, 2xHU256, 2 HU80, 2xU20), the effects on the beam have been studied (closed orbit distortions, tune shifts,..), compared with the expectations from magnetic measurements in laboratory, and compensated using feed forward local correctors. The radiation observed on the first photon diagnostic at the beamlines is also analysed.

The French 3rd generation synchrotron light source, SOLEIL, was successfully commissioned in 2006. The Linac and the Booster are operational at their design performances. During the early phase of the storage ring commissioning, the essential design parameters were reached very quickly while the project incorporates some innovative techniques such as the use of a superconducting RF cavity, solid state RF amplifiers, NEG coating for all straight parts of the storage ring 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, were installed on the ring. The main results of the commissioning will be reviewed here, including discussion on diagnostics performances, orbit stability and control, optics correction, Top-up and the challenges in achieving operational status. The 10 beamlines of phase 1 are now under commissioning and regular user operation will start by spring 2007.
