Energy selective imaging using cold neutron at NIST

Radiation imaging using neutron can give special information about the object that x-ray imaging doesn't see. One of the special information is energy selective neutron imaging. This imaging technology uses the Bragg-edges of crystalline materials. So it has advantages that the microstructural information related to the lattice length such as phase and strain without destruction of the objects. In this paper, energy selective imaging experiment using cold neutron is performed in NG-6 at NIST. Neutron imaging technique can be useful method for internal structure analysis of the materials. This method can be possible to check that the phases of the materials without destruction. This experimental results are simply divided the two images, but the further analysis and progresses will be proceeded with PNU and NIST
