Status of the SOLEIL Booster Synchrotron

SOLEIL is a 2.75 GeV third generation synchrotron radiation facility under construction near Paris [1]. The injection system is composed of a 100 MeV electron Linac pre-accelerator followed by a full energy (2.75 GeV) booster synchrotron. The booster lattice is based on a FODO structure with missing magnet. With a circumference of 157 m and low field magnets (0.74 T), the emittance reaches 150 nm. rad at 2.75 GeV. A flexible and economic ramping switched mode procedure was chosen for the main power supplies cycled up to 3 Hz and a 35 kW-352 MHz solid state amplifier provides the RF power. At present time we are in an intensive equipments test phase and we plan to commission the booster with beam by June 2005.
