IFEFFIT : interactive XAFS analysis and FEFF fittingJournal of Synchrotron Radiation - Tập 8 Số 2 - Trang 322-324 - 2001
M. Newville
IFEFFIT, an interactive program and scriptable library of XAFS algorithms is
presented. The core algorithms of AUTOBK and FEFFIT have been combined with
general data manipulation and interactive graphics into a single package.
IFEFFIT comes with a command-line program that can be run either interactively
or in batch-mode. It also provides a library of functions that can be used
easily from C or Fo... hiện toàn bộ
EXAFS analysis using FEFF and FEFFITJournal of Synchrotron Radiation - Tập 8 Số 2 - Trang 96-100 - 2001
M. Newville
Some of the advanced EXAFS analysis features of FEFF and FEFFIT are described.
The scattering path formalism from FEFF and cumulant expansion are used as the
basic building blocks of EXAFS analysis, giving a flexible and robust
parameterization of most EXAFS problems. The ability to model EXAFS data in
terms of generalized physical variables is shown, including the simultaneous
refinement of two d... hiện toàn bộ
The vacuum ultraviolet beamline/endstations at NSRL dedicated to combustion researchJournal of Synchrotron Radiation - Tập 23 Số 4 - Trang 1035-1045 - 2016

An undulator-based vacuum ultraviolet (VUV) beamline (BL03U), intended for
combustion chemistry studies, has been constructed at the National Synchrotron
Radiation Laboratory (NSRL) in Hefei, China. The beamline is connected to the
newly upgraded Hefei Light Source (HLS II), and could deliver photons in the
5–21 eV range, with a photon flux of 1013 photons s−1at 10 eV when the beam
current is 300 ... hiện toàn bộ
Single-crystal diamond refractive lens for focusing X-rays in two dimensionsJournal of Synchrotron Radiation - Tập 23 Số 1 - Trang 163-168 - 2016
Sergey Antipov, Sergey V. Baryshev, J. E. Butler, Olga Antipova, Z. Liu, Stanislav Stoupin
The fabrication and performance evaluation of single-crystal diamond refractive
X-ray lenses of which the surfaces are paraboloids of revolution for focusing
X-rays in two dimensions simultaneously are reported. The lenses were
manufactured using a femtosecond laser micromachining process and tested using
X-ray synchrotron radiation. Such lenses were stacked together to form a
standard compound re... hiện toàn bộ
