ABSTRACT

BL46XU is an industrial applications beamline with an undulator light source and used for promoting utilization of synchrotron radiation by industry. A multi-axis X-ray diffractometer and hard X-ray photoemission spectroscopy device has been installed in the experimental hutch. The XPS device can be replaced by a small x-ray diffractometer for structure evaluation of thin films in a simple exchange procedure within the experimental hutch.
Using the multi-axis X-ray diffractometer (HUBER 8-axis diffractometer), you can carry out not only general X-ray diffraction/scattering measurement but also grazing-incident X-ray diffraction and X-ray reflectivity measurement to characterize structure of thin films, surface, and interface or residual strain measurement by X-ray diffraction. There are various utilities in the peripheral devices to meet a variety of analytical needs from users. For example, a two-dimensional pixel detector allows you to perform in-situ time-resolved X-ray diffraction experiments.
The hard X-ray spectroscopy system utilizes hard X-ray (6-8keV) from high brilliance synchrotron radiation of SPring-8 to excite high-energy photoelectrons with a large escape depth, achieving probing depth of 20nm that is sufficient for the electronic state analysis deep inside the material.

SOURCE AND OPTICS

Light source is a standard in-vacuum undulator in SPring-8 and optics adopts a Si (111) direct water-cooled inclined double-crystal monochromator. The tunable energy range is 6-35 KeV. Two Rh-evaporated mirrors (70cm length, reflection direction is horizontal) are placed in the most downstream part of the optics hutch to eliminate harmonics. The mirrors have curvature for horizontal light focus. A Si (111) channel-cut monochromator is placed between the monochromator and the mirrors to get incident X-ray with fine energy resolution for hard X-ray photoemission spectroscopy.
