Materials Science, Physics
Beamline POLAR focuses on polarization dependent spectroscopy and scattering studies of magnetic materials in the hard x-rays. This beamline is equipped with crystal phase retarding optics that allow the user to manipulate the polarization of the incoming x-ray beam on the sample (i.e., linear to circular (Pc ~ 0.98) or horizontal linear to vertical linear (Plin ~ -[0.80-0.95]).
