Abstract
Neutron and X-ray CT are powerful nondestructive testing techniques, they can penetrate sample, interact with the material, and comes out internal structure information in three dimensions. However, as the neutrons and X-rays interact with elements by different mechanisms, imaging by them can be used to provide a better understanding of the samples. The Energy-Resolved Neutron Imaging instrument (ERNI) in Chinese Spallation Neutron Source (CSNS) is equipped with in situ X-ray micro-CT which is used to combine neutron CT and provide more structure and composition information of sample. The designed best resolution of the X-ray imaging system is 2 micrometers when using the minimum operating power, also a favorable compensation for neutron imaging whose resolution is about 40 micrometers.
