Project: Advanced Neutron Radiography

Neutron radiography is an imaging technology which provides images similar to photon radiography and can be profitably used for several applications (e.g. determination of hydrogen distribution in materials, study of structural defects in materials, detection and identification of certain shielding materials that may be associated with nuclear threats).

The neutron and photon interaction mechanisms with matter are significantly different and offer complementary information. While photon attenuation in matter is directly dependent on atomic number, neutrons are efficiently attenuated by only a few specific elements. Materials with low atomic numbers, and particularly those containing high levels of hydrogen such as water and organic materials are clearly visible in neutron radiographs.

I worked on the development of a filter-difference based technique, i.e. a technique able to detect different elements within a sample by means of subtracting various transmission images of the sample obtained with different interposed filters.

In order to test this technique, I also developed a laboratory prototype neutron radiography instrument with the Low Energy Neutron Source (LENS), at the Indiana University Cyclotron Facility, that produces neutron beams of relatively low energy (around 10 MeV).
