John P. Barton
John Penrose Barton (born 1934) is a British and American applied nuclear scientist who helped pioneer Neutron Radiography. Neutron Radiography (aka Neutron Imaging) is a new way of seeing (imaging) things complementary to Radiography with X-Rays. Particularly notable applications are to Aviation safety such as inspection of jet engine turbine blades. Barton chaired or co-chaired the first four World Conferences on Neutron Radiography held in San Diego, 1981; Paris, 1986; Osaka, 1989 and San Francisco, 1992. Early years Barton was born in London in 1934. He studied Applied Nuclear Physics under Philip Burton Moon and Rudolf Peierls at the University of Birmingham. From 1957 he worked on the neutron physics of power reactor design at AERE Harwell, where John Cockcroft was head of laboratory. Barton worked at AEE Winfrith from 1959 to 1960. Pioneering Neutron Radiography Internationally From 1961 to 1965, while affiliated with the University of Birmingham, Barton's publication ...

Neutron Imaging
Neutron imaging is the process of making an image with neutrons. The resulting image is based on the neutron attenuation properties of the imaged object. The resulting images have much in common with industrial X-ray images, but since the image is based on neutron attenuating properties instead of X-ray attenuation properties, some things easily visible with neutron imaging may be very challenging or impossible to see with X-ray imaging techniques (and vice versa). X-rays are attenuated based on a material's density. Denser materials will stop more X-rays. With neutrons, a material's likelihood of attenuation of neutrons is not related to its density. Some light materials such as boron will absorb neutrons while hydrogen will generally scatter neutrons, and many commonly used metals allow most neutrons to pass through them. This can make neutron imaging better suited in many instances than X-ray imaging; for example, looking at O-ring position and integrity inside of metal co ...

Sacramento Air Logistics Center
Sacramento Air Logistics Center is a former United States Air Force unit based at McClellan Air Force Base from 1935 until its closure as part of the 1995 Base Realignment and Closure Commission. History Construction of the Pacific Air Depot began in 1935, and the main structures, including administrative buildings, barracks, warehouses and a hospital were completed on 18 April 1938. It was one of only four such air Main Operating Base, depots in the country. In 1938 the base was renamed Sacramento Air Depot and underwent a major expansion as a repair and overhaul facility for P-38 and P-39 fighter planes. The planes were serviced on an assembly line basis. In 1940, an assembly line was added to overhaul P-40 fighters. In December 1941, soon after the attack on Pearl Harbor, P-40s as well as B-26 Marauder, B-26 and B-17 Flying Fortress, B-17 bombers began arriving at the field to be armed and prepared for immediate shipment overseas. Some B-17s came direct to McClellan from the fac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Diego
San Diego ( , ; ) is a city on the Pacific Ocean coast of Southern California located immediately adjacent to the Mexico–United States border. With a 2020 population of 1,386,932, it is the eighth most populous city in the United States and the seat of San Diego County, the fifth most populous county in the United States, with 3,338,330 estimated residents as of 2019.

Idaho National Laboratory
Idaho National Laboratory (INL) is one of the national laboratories of the United States Department of Energy and is managed by the Battelle Energy Alliance. While the laboratory does other research, historically it has been involved with nuclear research. Much of current knowledge about how nuclear reactors behave and misbehave was discovered at what is now Idaho National Laboratory. John Grossenbacher, former INL director, said, "The history of nuclear energy for peaceful application has principally been written in Idaho". Various organizations have built more than 50 reactors at what is commonly called "the Site", including the ones that gave the world its first usable amount of electricity from nuclear power and the power plant for the world's first nuclear submarine. Although many are now decommissioned, these facilities are the largest concentration of reactors in the world. It is on a complex in the high desert of eastern Idaho, between Arco to the west and Idaho ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transient Reactor Test Facility
The Transient Reactor Test Facility (TREAT) is an air-cooled, graphite moderated, thermal spectrum test nuclear reactor designed to test reactor fuels and structural materials. Constructed in 1958, and operated from 1959 until 1994, TREAT was built to conduct transient reactor tests where the test material is subjected to neutron pulses that can simulate conditions ranging from mild transients to reactor accidents. TREAT was designed by Argonne National Laboratory, and is located at the Idaho National Laboratory. Since original construction, the facility had additions or systems upgrades in 1963, 1972, 1982, and 1988. The 1988 addition was extensive, and included upgrades of most of the instrumentation and control systems. The U.S. Department of Energy (DOE) decided to resume a program of transient testing, and planned to invest about $75 million to restart the TREAT facility by 2018. The renewed interest in TREAT was sparked by the 2011 Fukushima Daiichi nuclear disaster, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argonne National Laboratory
Argonne National Laboratory is a science and engineering research national laboratory operated by UChicago Argonne LLC for the United States Department of Energy. The facility is located in Lemont, Illinois, outside of Chicago, and is the largest national laboratory by size and scope in the Midwest. Argonne had its beginnings in the Metallurgical Laboratory of the University of Chicago, formed in part to carry out Enrico Fermi's work on nuclear reactors for the Manhattan Project during World War II. After the war, it was designated as the first national laboratory in the United States on July 1, 1946. In the post-war era the lab focused primarily on non-weapon related nuclear physics, designing and building the first power-producing nuclear reactors, helping design the reactors used by the United States' nuclear navy, and a wide variety of similar projects. In 1994, the lab's nuclear mission ended, and today it maintains a broad portfolio in basic science research, energy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radiography
Radiography is an imaging technique using X-rays, gamma rays, or similar ionizing radiation and non-ionizing radiation to view the internal form of an object. Applications of radiography include medical radiography ("diagnostic" and "therapeutic") and industrial radiography. Similar techniques are used in airport security (where "body scanners" generally use backscatter X-ray). To create an image in conventional radiography, a beam of X-rays is produced by an X-ray generator and is projected toward the object. A certain amount of the X-rays or other radiation is absorbed by the object, dependent on the object's density and structural composition. The X-rays that pass through the object are captured behind the object by a detector (either photographic film or a digital detector). The generation of flat two dimensional images by this technique is called projectional radiography. In computed tomography (CT scanning) an X-ray source and its associated detectors rotate around ...
