摘要：

Neutron resonance absorption spectroscopy (N-RAS) associated with computer tomography was applied to thermometry for an inhomogeneous bulk object. This new method provides two-dimensional distributions of nuclide temperatures on the planar cross-section of an object as information from remote-sensing analysis. The experimental result showed good agreement with the actual temperature distribution inside the object, and the simulation of the experiment correctly reproduced the result. For greater accuracy, we need to achieve finer spatial resolution and better statistical reliance on N-RAS. The development of this novel approach has links to new industrial applications utilizing neutrons for remote sensing and non-destructive thermometry. (c) 2005 Elsevier B.V. All rights reserved.
