Technical details
The XMaS beamline can be operated in 3 different modes: (1) focused and monochromatic beam (2.4-15 keV), (2) unfocused and monochromatic beam (2.4-25 keV), (3) white beam (2.4-50 keV and above). At present, the beamline only uses a focused and monochromatic beam. XMaS also possesses a special cryostat and pumping system especially designed for actinides and transuranics, such as depleted uranium, plutonium, neptunium and cerium. X-ray scattering modes include resonant, non-resonant and magnetic scattering. Magnetic X-ray reflectivity measurements are also possible. The WAXS geometry is grazing incidence.
