UE49_SGM

Soft X-ray undulator radiation variable polarization with SGM for excited state dynamics at EDAX

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 µm liquid jet soft X-ray spectroscopy with full polarization control.
