ID32 - Soft X-ray spectroscopy

Synopsis

XMCD branch with plane grating monochromator and variable spot size at the sample. RIXS branch with very high resolving power (aim combined RP=30000) and 10m spectrometer with constant variable scattering angle over 100 degrees. Open experimental area with the possibility of installing user chambers or using beamline instruments for example for soft x-ray diffraction or coherence experiments
