Grazing-Exit X-ray Analysis

are needed. Since the analysis depth depends on the accelerating voltage of the electron beam, the application of low accelerating voltages limits the characteristic-X-ray generation region to a minute region near the specimen surface. However, the energies of the X-rays are less than those of the accelerated electrons; this causes a new problem: the use of analytical X-ray lines is limited. Th...

Forty Years of X-Ray Binaries

In 2012 it was forty years ago that the discovery of the first X-ray binary Centaurus X-3 became known. That same year it was discovered that apart from the High-Mass X-ray Binaries (HMXBs) there are also Low-Mass X-ray Binaries (LMXBs), and that Cygnus X-1 is most probably a black hole. By 1975 also the new class of Be/X-ray binaries was discovered. After this it took 28 years before ESAs INTE...

Bayesian inversion method for 3D dental X-ray imaging

Diagnostic and operational tasks in dentistry require three-dimensional (3D) information about tissue. A novel type of low dose dental 3D X-ray imaging is considered. Given projection images taken from a few sparsely distributed directions using the dentist’s regular X-ray equipment, the 3D X-ray attenuation function is reconstructed. This is an ill-posed inverse problem, and Bayesian inversion...

Bayesian soft X-ray tomography using non-stationary Gaussian Processes.

In this study, a Bayesian based non-stationary Gaussian Process (GP) method for the inference of soft X-ray emissivity distribution along with its associated uncertainties has been developed. For the investigation of equilibrium condition and fast magnetohydrodynamic behaviors in nuclear fusion plasmas, it is of importance to infer, especially in the plasma center, spatially resolved soft X-ray...
