Abstract

Abstract: A moveable multi-use neutron imaging facility was constructed based on a compact accelerator D-T neutron source, for use in thermal and fast neutron radiography and tomography. Experiments were carried out to investigate the imaging quality for different standard samples. The smallest width of a slit that can be tested by digitized thermal neutron radiography was found to be 0.06 mm, while the smallest diameter of holes tested by digitized fast neutron radiography was 0.5 mm. A gadolinium wire of 0.2 mm in diameter within a multi-material structure was reconstructed clearly with thermal neutron tomography, and holes in a light material were reconstructed with fast neutron tomography. Highlights: An imaging facility using a D-T neutron source based on compact accelerator is presented. Thermal and fast neutron radiography and tomography were carried. Digitized thermal and fast neutron radiography can respectively test a 0.06 mm-width slit and a 0.5 mm-diameter hole. Thermal and fast neutron tomography can respectively test a 0.2 mm-diameter gadolinium wire and light material's holes.
