Abstract
Neutron tomography was studied using a neutron resonance absorption spectrometer installed on a pulsed neutron source. The neutron resonance absorption spectroscopy (N-RAS) is a method to study the dynamics of nuclides by analyzing the Doppler broadening of their resonance spectra. N-RAS can combine with the computer tomography (CT) technique to obtain the tomogram of an object. We developed the CT reconstructions which were repeated at each time-of-flight (TOF) channel and piled up the reconstructed images in order to make the resonance spectrum over the wide energy range. Finally, we could deduce the information of nuclides and its temperature distributions in the sample non-destructively. We call this new TOF tomography technique as neutron resonance imaging (NRI).
