Particle Induced X-ray Emission
Electron in orbit around the nucleus,
in quantized energy level.
Protons from the accelerator
impinge upon the target.
Interaction with the passing proton
excites the electron into a higher energy
The atom spontaneously de-excites,
releasing the excess energy in the form
of an X-ray.
Tandem FN Accelerator
PIXE is a non-destructive technique.
It is a fairly easy technique to use.
The process allows for analysis below the surface of the
PIXE allows researchers to see trace elements within

There is no Sulfur in the chipped spots, but it appears in all of
the other runs.
All of the runs have Ca, K, and Fe.
There is an increase in the amount of Cobalt seen in the blue
pigments compared to the other colors.
There is a notable presence of Lead in all of the runs.
There is a difference in the concentrations of the elements for different
samples, even for runs on the same color.
