摘要：
Neutron tomography was studied using the neutron resonance absorption spectrometer installed on the 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 cross sectional image of the sample. We develop the method as detailed analysis of time-of flight (TOF) resonance absorption spectra. The CT reconstructions are repeated at each TOF channel and pile up the reconstructed images in order to make the resonance spectrum over the wide energy range. Finally, we can deduce the information of nuclides and its temperature distributions in the sample non-destructively. We call this new technique as neutron resonance imaging (NRI).
