Available in PDF, EPUB and Kindle. Book excerpt: The Air Force maintains facilities at the Sacramento Air Logistics Center containing a Maneuverable Neutron Radiography Inspection System, procured to detect hidden corrosion without disassembly of aircraft, and a Stationary Neutron Radiography Inspection System, procured to detect hidden corrosion in components removed from aircraft. The Maneuverable system became operational in December 1989. The Stationary system became operational in April 1991. The cost to develop and construct the systems was $23.8 million. Our objective was to evaluate the effectiveness of the neutron radiography inspection systems' ability to reduce maintenance costs. Specifically, we determined if joint use by all Military Departments would reduce DoD's weapon system maintenance costs. We also evaluated compliance with laws and regulations and the effectiveness of applicable internal controls.

This book was released on 1970 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recently developed neutron radiography facility at the Air Force Institute of Technology Nuclear Engineering Center, Wright-Patterson Air Force Base, Ohio, was evaluated to determine its suitability for critical application to problems in inspection and analysis by Air Force scientists and contractors. The transfer technique using indium foil converter screens was used. Primary emphasis was placed upon the optimization of radiographic image sharpness using a specially designed resolution test object and advanced techniques for image analysis. (Author).

This book was released on 2006 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Neutron radiography is a non-destructive analysis tool that complements X-ray transmission radiography. The use of neutrons provides the ability to image the interior of an object that has a metal core of steel or lead that would shield the interior from X-ray inspection. Neutron tomography is the use of a set of images of a single sample taken at various angles to produce a three dimensional rendition of the sample that greatly increases the effectiveness of neutron radiography as a non-destructive testing tool. A neutron radiography and tomography system has been built at the 1.1 MW TRIGA Mark II nuclear research reactor at The University of Texas at Austin in the Nuclear Engineering Teaching Lab. The Texas Neutron Imaging Facility is located on beam port five of the reactor and is housed in a shielding cave made of concrete to minimize radiation dose to users. The system itself integrates a sample positioning system and neutron sensitive camera through the use of a control code written in National Instruments Labview software. The code was written to increase the efficiency of the imaging process and to provide flexibility in the system. Precise sample positioning and timing of image acquisition provided by the code allows for the collection of data that can be used in computed tomography. The system has produced results in the form of radiographs and 3-D reconstructions of sample objects.
