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"
Optical layout of the SGM beamline at the undulator UE52.

Photon flux versus photon energy for the three gratings with 900, 1200 and with 1500 l/mm and with,
from top to bottom, horizontally, vertically and circularly polarized light (for an exit slit width of 20 µm).
Resolving power of UE52-SGM versus photon energy as covered by the 1st, 3rd and 5th undulator harmonics
for the three gratings of the monochromator and for two representative settings of the exit slit (10 and 20 µm).
