Abstract

The beamline BL7B at the UVSOR facility for solid-state spectroscopy is currently under reconstruction. This reconstruction mainly involves the replacement of the 1 m Seya–Namioka-type monochromator (50–600 nm) with a 3 m NIM (modified version of McPherson model 2253), which covers the 50–1000 nm range with three gratings. The deviation angle of the gratings is 15°. For linear and circular polarization experiments, the beamline optics consist of a two-grazing-incidence (87.5°) pre-mirror system and a normal-incidence (15°) post-mirror.
