XRB continuum fitting with sensitive high-energy X-ray detectors

Improving the energy resolution of bent crystal X-ray spectrometers with position-sensitive detectors

Wavelength-dispersive high-resolution X-ray spectrometers often employ elastically bent crystals for the wavelength analysis. In a preceding paper [Honkanen et al. (2014). J. Synchrotron Rad. 21, 104-110] a theory for quantifying the internal stress of a macroscopically large spherically curved analyser crystal was presented. Here the theory is applied to compensate for the corresponding decrea...

Method for Dual High Energy X-ray Imaging with Flat Panel Detectors

Dual-energy X-ray imaging in the keV range is a well-known technique e.g. used in baggage scanning. It requires two measurements at different energies and/or detector efficiencies and allows displaying material properties as the effective atomic number and mass density. The method thus provides the information allowing identifying illicit materials such as explosives and contraband or high-Z ma...

Modeling the X-ray contribution of XRB jets

Astrophysical jets exist in both XRBs and AGN, and seem to share common features, particularly in the radio. While AGN jets are known to emit X-rays, the situation for XRB jets is not so clear. Radio jets have been resolved in several XRBs in the low/hard state, establishing that that some form of outflow is routinely present in this state. Interestingly, the flat-to-inverted radio synchrotron ...

Design Consideration on Position Sensitive Detectors Based on LuAG:Pr Scintillators for High Energy X-ray Cargo Inspection

To prevent illegal trade of weapons, X-ray scanning systems are used for non-intrusive inspection of import containers and cargoes at every seaport and airport. Conventional X-ray scanning system for cargoes is based mainly on X-rays of several MeV energy generated by an electron Linac. For high quality X-ray imaging, an X-ray source with good directionality, narrow width of energy spectrum and...
