Development and comparison of techniques for two-dimensional analysis using the Harwell nuclear microprope

A Geant4 simulation of X-ray emission for three-dimensional proton imaging of microscopic samples

“…A complementary approach, providing a straightforward in depth localization, is brought by tomography. PIXE tomography was carried out for the first time in the early 1980's [4], with main applications in biology and material science [5]. To do this, the beam is scanned over the area of interest and, once the scan is complete, the sample is rotated through a small angle to perform the next scan.…”
