Abstract :
We have combined a toroidal and a KB mirror system in tandem to improve the focal spot size for the momentum-resolved inelastic X-ray scattering (IXS) spectrometer at Sector 3 in APS. This combination provides a factor of 40 gain in flux density and 20 μm (H)×17 μm (V) (FWHM) in beam size at the sample position, enhancing the capability of the beamline for high-pressure measurements.
