Title SYNCHROTRON SOLEIL SUPERCONDUCTING RF STATUS.
Type Poster cavity design / fabrication / treatment
Abstract The RF system of the Synchrotron SOLEIL light source involves superconducting cavities and solid state amplifiers. Two cryomodules are needed to provide the maximum power of 650 kW, required with the full beam current of 500 mA, at the nominal energy of 2.75 GeV and all the insertion devices.  A prototype cryomodule, housing two 352 MHz superconducting single-cell cavity with strong damping of the HOM, has been built and successfully tested in the ESRF storage ring.  Even though the achieved performance does meet the SOLEIL requirement for the 1st year of operation, the cryomodule prototype will be refurbished (insertion of a thermal copper shield cooled with liquid nitrogen, improvement of the HOM dipolar couplers, modification and lengthening of the fundamental power coupler antenna to achieve a Qext of 1105). A second cryomodule will be built and installed about one year later. Each of the four cavities will be powered with a 200 kW solid state amplifier consisting in a combination of  320 W elementary modules. The amplifier modules, based on a technology developed in house (with integrated circulator and individual power supply), will be fabricated in the industry. A 40 kW solid state amplifier (146 modules) for the booster is being assembled and should be tested on a dummy load, before the end of 2003.
