Abstract
BL37XU (trace element analysis beamline) and BL39XU (magnetic materials beamline) at SPring-8 have been upgraded to provide nano-probe analysis. We designed and installed Kirkpatrick-Baez (KB) mirrors and corresponding manipulators, which have an X-ray focusing beam as small as 100 nm. To realize a high-flux 100-nm focusing beam, a high-demagnification optical design was used, and new experimental hutches were constructed that are located about 80 m from the light source. By taking advantage of extended beamline, focusing photon flux density of over 1 x 109(photons/sec/100x100nm2) is possible with a working distance of 100 mm at X-ray energy of around 10 keV. The current status of these beamlines is reported.
