| | The 352 MHz RF accelerating systems for the SOLEIL
Booster (BO) and Storage Ring (SR) are in operation
since mid 2006. In the BO, a 5-cell copper cavity of the
CERN-LEP type is powered with a 35 kW solid state
amplifier. In the SR, the required RF accelerating voltage
(up to 4.4 MV) and power (560 kW at full beam current
of 500 mA) will be provided by two cryomodules, each
containing a pair of superconducting cavities, specifically
designed for SOLEIL. The first cryomodule is operational,
while the second one, which is being constructed by
ACCEL (Germany), will be implemented in May 2008.
Both cryomodules are cooled down to 4.2 K with liquid
helium from a single 350 W liquefier and each cavity is
powered by a 180 kW solid state amplifier. Using a single
cryomodule and two amplifiers, the first objective of
storing 300 mA stable beam was successfully achieved in
2006. The RF system commissioning and operation
results are reported. | |
