Simulations of X-ray bursts and superbursts [PDF]
, 2015 Observations of neutron star in binary systems provide powerful constrains on the physics at the surface of neutron stars. During the accretion of matter from the companion star, periodic nuclear explosion are triggered in the outer layers of the neutron

Diagnosing and mapping pulmonary emphysema on X-ray projection images [PDF]
, 2013 To assess whether grating-based X-ray dark-field imaging can increase the sensitivity of X-ray projection images in the diagnosis of pulmonary emphysema and allow for a more accurate assessment of emphysema distribution.

The effect of proton damage on the X-ray spectral response of MOS CCDs for the swift X-ray telescope [PDF]
, 2002 The effect of non-ionising energy loss(NIEL) of protons in charge-coupled devices is to displace silicon atoms and any dopant materials present from their lattice positions to form lattice defects which in turn can trap electrons [1].

Coherent Compton X-Ray Sources [PDF]
Journal of X-Ray Science and Technology: Clinical Applications of Diagnosis and Therapeutics, 1994 Coherent x rays can be produced by scattering of laser light by a beam of relativistic electrons, provided that the electron beam is density modulated or the scattering is done at, or near, 90°. Since the coherent scattering is proportional to N 2 , where N is the number of electrons, and the
