X-ray scattering from a plane parallel slab using radiation transfer considerations [PDF]

open access: yesarXiv, 2020
X-ray scattering power of a plane parallel homogeneous slab of material is derived using radiation intensity transfer equations.The scattering power scales with the ratio of the scattering coefficient of interest to the total attenuation coefficient. The results can be used to guide the choice of slab thickness, scattering geometry and photon energy to

Robust, high-throughput solution structural analyses by small angle X-ray scattering (SAXS)

open access: yesNature Methods, 2009
We present an efficient pipeline enabling high-throughput analysis of protein structure in solution with small angle X-ray scattering (SAXS). Our SAXS pipeline combines automated sample handling of microliter volumes, temperature and anaerobic control ...

X-ray Raman scattering study of aligned polyfluorene [PDF]

open access: yes, 2006
We present a non-resonant inelastic x-ray scattering study at the carbon K-edge on aligned poly[9,9-bis(2-ethylhexyl)-fluorene-2,7-diyl] and show that the x-ray Raman scattering technique can be used as a practical alternative to x-ray absorption measurements.

Simultaneous high-resolution scanning Bragg contrast and ptychographic imaging of a single solar cell nanowire [PDF]

open access: yes, 2015
Simultaneous scanning Bragg contrast and small-angle ptychographic imaging of a single solar cell nanowire are demonstrated, using a nanofocused hard X-ray beam and two detectors.

HEW simulations and quantification of the microroughness requirements for X-ray telescopes by means of numerical and analytical methods [PDF]

open access: yesProceedings of the SPIE, Optics for EUV, X-Ray, and Gamma-Ray Astronomy III, Vol. 6688, 66880H (2009), 2015
Future X-ray telescopes like SIMBOL-X will operate in a wide band of the X-ray spectrum (from 0.1 to 80 keV); these telescopes will extend the optical performances of the existing soft X-ray telescopes to the hard X-ray band, and in particular they will be characterized by a angular resolution (conveniently expressed in terms of HEW, Half-Energy- Width)

On the ratio of the relativistic electron PXR in the Bragg direction and in the forward direction in Laue geometry [PDF]

open access: yes, 2010
Parametric X-ray radiation and parametric X-ray radiation at a small angle with respect to the velocity of a relativistic electron crossing a single crystal plate in Laue scattering geometry are studied based on the dynamic X-ray diffraction ...

Pepsi-SAXS: an adaptive method for rapid and accurate computation of small-angle X-ray scattering profiles.

open access: yesActa Crystallographica Section D: Structural Biology, 2017
A new method called Pepsi-SAXS is presented that calculates small-angle X-ray scattering profiles from atomistic models. The method is based on the multipole expansion scheme and is significantly faster compared with other tested methods.
