Geant4 simulations of soft proton scattering in X-ray optics. A tentative validation using laboratory measurements [PDF]

open access: yes, 2017
Low energy protons (< 300 keV) can enter the field of view of X-ray space telescopes, scatter at small incident angles, and deposit energy on the detector, causing intense background flares at the focal plane or in the most extreme cases, damaging the X ...

On inverse scattering for the multidimensional relativistic Newton equation at high energies [PDF]

open access: yes, 2006
Consider the Newton equation in the relativistic case (that is the Newton-Einstein equation) $$\eqalign{\dot p = F(x),& F(x)=-\nabla V(x),\cr p={\dot x \over \sqrt{1-{|\dot x|^2 \over c^2}}},& \dot p={dp\over dt}, \dot x={dx\over dt}, x\in C^1(\R,\R^d),}\

Free radical decay and micro-structure evolution of PVDF membranes in situ irradiated by synchrotron radiation X-ray

open access: yesPolymer Testing, 2022
The synchrotron radiation X-ray was used both as the irradiation source and testing tool for the PVDF membranes in-situ. The structural evolution of the PVDF membranes irradiated by the synchrotron radiation X-ray was analyzed by in-situ small angle X ...

Correlated Diffuse X-ray Scattering from Periodically Nano-Structured Surfaces [PDF]

open access: yes, 2016
Laterally periodic nanostructures were investigated with grazing incidence small angle X-ray scattering. To support an improved reconstruction of nanostructured surface geometries, we investigated the origin of the contributions to the diffuse scattering
