Beamline description

The undulators

The beamline receives light from two elliptically polarized undulators, covering the low/intermediate and intermediate/high photon energy range. Both undulators will allow a full control of the incoming light polarization.
LEU and HEU provide two sources that are separated by 2.4 m.

•  Low-Energy Undulator: LEU:  (APU: Adjustable Phase Undulator, fixed gap)
-     Photon energy range: 9 eV - 250 eV (H1, 2GeV)
-     Period length = 132 mm, number of periods = 18

•     High-Energy Undulator HEU (EPU: Elliptically Polarizing Undulator)
-     Photon energy range: 84 eV - 700 eV (H1, 2 GeV); up to 3 keV (H5, 2.4 GeV)
-     Period length = 50.36 mm, number of periods = 28
