Foundations and trends of high resolution energy dispersive PIXE (HiRED-PIXE) [PDF]
Nuclear Instruments & Methods in Physics Research B, 2020 High Resolution Particle Induced X-ray Emission, for short HR-PIXE, dates back to 1977 and is, therefore, nearly as old as standard PIXE itself.

XRF induced by PIXE: Comparison with PIXE
Journal of Radioanalytical and Nuclear Chemistry Letters, 1987Two different modes of sample excitation have been used for elemental analysis of thin standard reference materials and of chemical standards with known composition. PIXE /2.5 MeV protons/ and XRF induced by PIXE, will be called XRF-PIXE /2.5 MeV protons on Mo primary target/. The same samples were alternatively exposed to protons and X-ray beams.

μ-PIXE and X-PIXE for radiological forensics
SPIE Proceedings, 2005Sandia is evaluating methods for identifying and quantifying trace signatures in field collection samples to support national deterrence policies. The first step in this process is to identify which combination of major, minor, and trace elements in a recovered collection sample provides the most reliable forensic information, and then to be able to ...

Particle induced X-ray emission (PIXE) is an important physical effect that is not yet adequately modelled in Geant4. This paper provides a critical analysis of the problem domain associated with PIXE simulation; it evaluates the conceptual approach, design and implementations of PIXE modelling so far available in Geant4, and describes a set of ...

The NeWS window server from Sun Microsystems is the addition of quasiparallelism to PostScript. NeWS uses this parallelism to deal with the inherent concurrency of human/computer interactions. NeWS provides multiple, lightweight processes to deal with this parallelism; as a result, user interfaces are demonstrably easier to implement using NeWS than ...

Applications of PIXE in the Life Sciences
Biological Trace Element Research, 1994During the last decade, particle-induced X-ray emission spectrometry (PIXE) has been accepted by the analytical chemistry community as a standard method. Instead of routine bulk analysis of biomedical samples where several competing analytical techniques are available, the full strength of PIXE could be exploited in special applications where also ...

External PIXE and mu-PIXE measurements of elemental concentrations in volcanic rocks
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1992Abstract PIXE measurements have been performed on volcanic rocks, using external 3 MeV proton beams of 50 to 200 μm diameter, at the KN3000 Van de Graaff accelerator of the Physics Department of the Florence University. Two or more Si(Li) detectors are used during each run and the elemental composition is computed from the peak areas obtained in the ...
