BL46XU OUTLINE

Inquiry number

INS-0000001484

ABSTRACT

BL46XU is an industrial applications beamline with an undulator source for promoting the utilization by industry. A Hard X-ray photoelectron spectroscopy (HAXPES) has been installed in the 2nd experimental hutch. The HAXPES system utilizes a hard X-ray range of 6-10 keV from high brilliance synchrotron radiation of SPring-8 to excite high-energy photoelectrons with a large probing depth of 20 nm. HAXPES is a powerful technique to elucidate the electronic structure of functional devices which have nanometer-sized layer structures. Because of the large probing depth, it is suitable for analyzing samples that have difficulty in surface cleaning.

SOURCE AND OPTICS

The X-ray source of BL46XU has equipped a standard in-vacuum undulator. A double-crystal Si (111) monochromator with a liquid-nitrogen cooling system was utilized to monochromatize synchrotron X-ray beams. X-rays with an energy range from 6 keV to 37 keV can be obtained with the undulator and the monochromator. Two Rh-coated mirrors (70 cm length) with a bending system were placed in the most downstream part of the optics hutch to focus the X-rays in the horizontal direction and eliminate the high-order harmonics. A Si (111) channel-cut monochromator (CCM) was placed between the monochromator and the mirrors to achieve the fine energy resolution of the incident X-ray for HAXPES.
