Abstract

Beamline UE49-SGM is a dedicated high-flux soft x-ray beamline, spanning the energy range of 95 eV to 1400 eV. Its micrometer focus makes it ideally suitable for investigation of small or inhomogeneous samples both with spectroscopic methods and coherent scattering as well as imaging techniques with full polarization control.

Highlights

  • The UE49SGM RICXS beamline is a dedicated high- ux-density beamline, which accomodates two permanent experimental set-ups for x-ray scattering: the Resonant Inelastic X-ray Scattering and the Coherent X-ray Scattering (CXS) end-stations

  • The μmRIXS experiment is designed for resonant X-ray Raman studies of solid samples under ultra-high vacuum conditions and in the temperature range from liquid He to room temperature

  • It is equipped with a confocal plane grating spectrometer, which allows optimizing the operation mode between high signal-transmission and high energy-resolution

Summary

Introduction

The UE49SGM RICXS beamline is a dedicated high- ux-density beamline, which accomodates two permanent experimental set-ups for x-ray scattering: the Resonant Inelastic X-ray Scattering (μmRIXS) and the Coherent X-ray Scattering (CXS) end-stations. The μmRIXS experiment is designed for resonant X-ray Raman studies of solid samples under ultra-high vacuum conditions and in the temperature range from liquid He to room temperature. It is equipped with a confocal plane grating spectrometer, which allows optimizing the operation mode between high signal-transmission and high energy-resolution. The characteristics of the RICXS beamline were designed to meet the high demands of the two techniques, which are high (coherent) photon ux, a μm-size beam focus and full polarization control (linear and circular) It can be operated in the energy range 95 – 1400 eV, covering the resonant transitions of many relevant elements, such as silicon and phosphor L-.
