UE52_SGM - Soft X-ray undulator radiation variable polarization with SGM and resonant bunch excitation for open

Soft x-ray beamline for flexible end stations with variable polarization covering the range of 100 - 1500 eV with an x-ray spot size of approximately 60 µm (horizontal). The polarization can be freely chosen between linear (any orientation) and circular. Resonant Pulse excitation allows for "single bunch on demand"
