Imaging

X-ray imaging is a well-established technique used for non-destructive testing on a huge variety of specimens. The field of applications for this valuable technique has been further expanded by the use of neutrons in radiography and tomography. Neutrons have a high penetration depth for many materials which are practically opaque for x-rays; furthermore, excellent and even isotope-specific contrast is achieved for many light materials. This fact renders neutron radiography and tomography powerful tools complementary to x-ray imaging techniques, which have encountered a tremendous increase in popularity in non-destructive testing applications. Furthermore, the magnetic moment of a neutron gives access to new methods such as the spatially resolved investigation of magnetic structures and magnetic fields, an area which up to now has been barely explored.
