Open Accesn Version

UE52 SGM is an open port beamline with a monochromator containing 3 spherical gratings covering the energy range of 100 to 1500 eV and allows for variable polarization (circular and in any orientation linear) with a focus of about 20 - 60 μm (horizontal) x beamline slit (vertical) spot in focus.
