  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.

  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.
