SOLEIL is a 2.75 GeV new third generation synchrotron radiation facility under construction near Paris. The injector system is composed of a 100 MeV electron Linac pre-accelerator followed by a full energy (2.75 GeV) booster synchrotron. A repetition rate of 3Hz is required for the booster for the filling of the Storage Ring together with the need for discontinuous operation for top-up filling mode. Based on digital regulation loop, the four power supplies (2 for the dipoles 600 A x 1000 V and 2 for the quadrupoles 250 A x 450 V) reach the current tracking tolerance specification of 10-3. The aim of this paper is to describe the main issues from the loads to the mains network through the power converters that are essential to reach the required performances.

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.

Eddy current thin septum magnets are used to inject or extract the electron beam to/from the Booster and to the Storage Ring of SOLEIL. Good transverse homogeneity in the gap for injected beam, and low leakage field on circulating beam is needed, as well as pulse stability. The Top Up injection mode of the Storage Ring needs a very low level of leakage field on the stored beam path. Operating currents are from 2000 A and 3000 A for Booster injection and extraction, to 5100 A for SR injection. This contribution will describe the magnets and the pulsed power supplies design. The electrical and magnetic measurement results will be presented, with a specific emphasis on the improvements needed to reduce the level of leakage field of the SR septum magnet.
