ABSTRACT

 BL09XU is dedicated to hard X-ray photoelectron spectroscopy (HAXPES). This beamline is a standard hard X-ray beamline with a 32 mm-period linear undulator and a liquid-nitrogen cooled monochromator. Different types of HAXPES instruments are installed in tandem in experimental hutch 1 and 2, allowing the use of each instrument depending on the purpose of measurement. In BL09XU, the advanced HAXPES measurement using the high-performance optical system is available, including double channel-cut monochromators, double x-ray phase retarders, long-length focusing mirrors, and so on. An example of measurement using these advanced optics is a resonant HAXPES measurement. By obtaining HAXPES spectra with sweeping the incident x-ray energy across an absorption edge, we can perform elemental and orbital selective electronic structure analysis.
