PLS EPU6 beamline for magnetic spectroscopy with circularly polarized soft X-ray

A 6-cm-period Elliptically Polarized Undulator (EPU6) beamline is being constructed at the Pohang Light Source (PLS) in Korea optimally designed for magnetic spectroscopy studies of materials in the soft X-ray region. This beamline is designed to cover the photon energy range 80–1800 eV with diverse polarization depending on the gap and phase of EPU6. The EPU6 monochromator is a DRAGON type Spherical Grating Monochromator (SGM) designed to provide maximum transmission and energy resolution at the 2p-absorption edges of transition metals and the 3d-, 4d-absorption edges of rare-earth materials.
