A compact experimental set up for neutron Tomography

Tomography with monochromatic neutrons can be performed with rather short flight paths having nonetheless a good medium spatial resolution. It is demonstrated that the appropriate use of a crystal monochromator having a certain mosaic spread improves remarkably the performance of the set up. This is of fundamental importance in the case of energy selective and Bragg edge neutron tomography, phase contrast tomography and tomography with polarized neutrons that all use narrow wave length bands
