Abstract
An inelastic x-ray scattering spectrometer has been implemented on the bending magnet beamline BM29
at the ESRF. It comprises a spherically bent perfect crystal as a Bragg analyser in near back reflection and a linear
position sensitive detector (PSD) in Rowland's geometry. The setup exploits the wide horizontal radiation fan from
a dipole magnet to create an extended source so that several eV of scattered radiation are simultaneously imaged
onto the PSD with a static analyser crystal. This is in contrast to existing configurations using undulator or wiggler
sources where one component of the emission spectrum is imaged and the analyser has to be scanned in angle. Results
are shown at the holmium Lm edge where the resolution is better than ~0.3 eV throughout the whole spectrum.
