2022 June - 9 articles

Cover Story: Under studied mechanisms contributing to the intensity of characteristic lines are described and discussed. Compton ionization of L and M shells, impact ionization from photoelectric and Compton secondary electrons, and the self-absorption of the higher energy Lorentzian tail at the absorption edge, are three effects that increase the height of the characteristic line produced by the dominant mechanism of inner-shell photoelectric ionization initiated by the primary photon. These additional contributions should be considered to obtain a better agreement between experimental and calculated characteristic intensities, and to improve the precision of the atomic parameters that require of an estimation of line intensity to be determined.

Fast Neutron Scintillator Screens for Neutron Imaging Using a Layered Polymer-Phosphor Architecture

  • William Chuirazzi,
  • Aaron Craft,
  • Burkhard Schillinger,
  • Jesus Mendoza,
  • Steven Cool and
  • Adrian Losko

Fast neutrons enable a nondestructive examination of dense, large, and highly attenuating samples due to their lower interaction probability compared to thermal neutrons. However, this also creates a challenge in fast neutron imaging, as the thicker...
