We have designed a large solid angle spectrometer mostly devoted to inelastic x-ray scattering (IXS) studies of materials under extreme conditions (high pressure / temperature) in the hard x-ray range. The new IXS spectrometer is designed to optimize the photon throughput while preserving an excellent resolving power of {approx}10000 in the considered energy range. The spectrometer consists of an array of up to 4 spherically bent 0.5 m radius analyzer crystals and a solid-state detector positioned on the Rowland circle. The four analyzers can cover a solid angle more than one order of magnitude larger than conventional spectrometers. The spectrometer is to be installed on the GALAXIES beamline at SOLEIL in the near future.
