Abstract
New-structure polycapillary x-ray optics for high pressure x-ray absorption fine structure (XAFS) absorption spectroscopy using the diamond anvil cells (DAC) method are applied in synchrotron radiation analysis. The optics are composed of a solid glass fiber in the center and surrounded by a hollow glass capillary array. They can restrain the higher harmonic of incident synchrotron radiation and obtain smooth and clear XAFS spectra. At the biological macromolecule station in the Beijing Synchrotron Radiation Facility (BSRF), a method of aligning these optics was developed and the transmission efficiency for both fundamental and higher harmonic waves investigated. The XAFS spectra of topological insulator material of Bi2Se3 were obtained by combining the optics.
