Radiography with neutrons can yield important information not obtainable by more traditional methods. In contrast to X-rays as the major tool of visual non-destructive testing, neutrons can be attenuated by light materials like water, hydrocarbons, boron, penetrate through heavy materials like steel, lead, uranium, distinguish between different isotopes of certain elements, supply high quality radiographs of highly radioactive components. These advantages have led to multiple applications of neutron radiography since 1955, both for non-nuclear and nuclear problems of quality assurance. The required neutron beams originate from radioisotopic sources, accelerator targets, or research reactors. Energy "tailoring" which strongly influences the interaction with certain materials adds to the versatility of the method. Since about 1970 norms and standards have been introduced and reviewed both in Europe (Birmingham, September 1973) and the United States (Gaithersburg, February 1975). The first world conference on neutron radiography will take place in December 1981, in San Diego, U.S.A. . In Europe the interested laboratories inside the European Community have entered into systematic collaboration through the Neutron Radiography Working Group (NRWGl. since May 1979. This Handbook has been compiled as one of the common tasks undertaken by the Group. Its principal authors are J.C. Domanus (Ris0 National Laboratory). and R.S. Matfield (Joint Research Centre, Ispra) Major contributions have been received from R. Liesenborgs (SCK/CEN Mol) R. Barbalat (CEN Saclayl.

Download High Resolution Neutron Imaging with Liglass Multicore Scintillating Fiber and Diffusion Studies to Enable Improved Neutron Imaging Book in PDF, ePub and Kindle
High resolution neutron imaging is an essential tool used for fundamental characterization of novel x-ray opaque microstructures. Currently, advanced neutron scattering facilities enable users to image materials with state-of-the-art neutron radiography spatial resolutions of approximately 10-15 microns. Continued progress towards micron resolution is limited by the intensity and the linearity of available thermal neutron fluxes. This places an emphasis on increasing neutron conversion/detection efficiency while maintaining the spatial accuracy of the projected radiograph.This dissertation reports the results of experimental fabrication and characterization of a microstructured multicore 6-lithium-glass scintillating fiber as a proof-of-concept high resolution neutron imager. The approach towards micron-level thermal neutron imaging and fundamental scintillator materials research for relevant imaging technologies are presented. Fabrication trials and neutron/gamma discrimination observations for an initial square-packed multicore design are described first. Then the fabrication process used for a proof-of-concept hexagonal-packed multicore design,and an evaluation of its radioluminescence and chemical stability is presented. Scintillation characteristics of a neutron imaging face plate were estimated, and its spatial resolution was experimentally measured. The ultimate resolving power of the proof-of-concept multicore was comparable to the state-of-the-art. The impact of even higher resolution designs, with potential to track neutron conversion particles using smaller core pitch or different cladding material, is discussed. Neutron imaging often requires nonlinear detection systems that can accurately represent the spatial features of an irradiated object. While thin film and microchannel plate detectors have been heavily researched for this application, little effort has been made to create selective scintillating regions within structured silicate glass detectors. This dissertation presents the continued research of diffusing trivalent cerium in lithium loaded glass. The creation of near surface regions of scintillation with thermal diffusion of the Ce3+ activator into 6Li glass is presented, and its use for neutron imaging with a bent optical fiber taper is discussed. The activation energy of Ce within the silicate is calculated and its valance state is observed as a function of diffusion depth. The diffusion process is then adopted for use with YAP (YAlO3:Ce) for associated particle imaging applications.
