The LERIX Spectrometer

The Lower Energy Resolution Inelastic X-ray scattering spectrometer (LERIX) was designed and constructed in Seidler's group at the University of Washington.  It was commissioned in 2006, and is now permanently stationed at Sector 20 XOR/PNC of the Advanced Photon Source X-ray Synchrotron.  This is the first spectrometer designed to perform rapid studies of q-dependent IXS with ~1eV energy resolution.  It has been used to study a wide range of problems, including especially problems associated with the local electronic structure in materials important for basic and applied energy sciences.
