Stable delivery of nano-beams for advanced nano-scale analyses

Abstract

Advanced nano-scale analyses such as X-ray absorption fine structure (XAFS), X-ray magnetic circular dichroism (XMCD) spectroscopy and X-ray fluorescence (XRF) with a ∼100 nm spatial resolution have been routinely conducted by upgrading two X-ray beamlines BL37XU and BL39XU at SPring-8. The focusing beam size can be varied from 50 nm to 2 μm and high flux achieved at 1012 photons/s/0.01% b.w. with the beam size of 300 × 300 nm2 (full width at half maximum) at 12 keV. © 2013 IOP Publishing Ltd.
