Abstract
A soft x‐ray beam line which enables high resolution and high flux at the same time is being developed at the Photon Factory for advanced characterization of new functional materials. The beam line is designed based on a cylindrical element monochromator (CEM) concept using undulator radiation from a 27‐pole multipole wiggler/undulator. The photon energy range of the beam line is 200–1000 eV which covers the core‐level excitation energy of carbon, nitrogen, and oxygen. Ray tracing simulation shows that the resolving power (λ/Δλ) is over 12 000 at 30 Å with a throughput of 25% when the opening of the exit slit is 10 μm. The beam line will supply x rays which facilitate both x‐ray absorption (XAS) and photoelectron (XPS) spectroscopic measurements with extremely high energy resolution.
