For the development of new materials by SR technology, a new beamline was d
esigned at the BL-7 of New SUBARU. This beamline consists of two branch lin
es, which are provided with an incident beam from a 3 m undulator by switch
ing the first mirror. One of them is a high photon-flux beamline with a mul
tilayered-mirror monochromator for the study of SR-process (BL7A) and anoth
er is a high-resolution beamline with a varied line spacing grating monochr
omator for the evaluation of nano-structure characteristics by SR-spectrosc
opy (BL7B). The useful range of emitted photons from 50 to 800 eV is covere
d at both beamlines. (C) 2001 Elsevier Science B.V. All rights reserved.
