Research Reactor
Research reactors are nuclear fission-based nuclear reactors that serve primarily as a neutron source. They are also called non-power reactors, in contrast to power reactors that are used for electricity production, heat generation, or maritime propulsion. Purpose The neutrons produced by a research reactor are used for neutron scattering, non-destructive testing, analysis and testing of materials, production of radioisotopes, research and public outreach and education. Research reactors that produce radioisotopes for medical or industrial use are sometimes called isotope reactors. Reactors that are optimised for beamline experiments nowadays compete with spallation sources. Technical aspects Research reactors are simpler than power reactors and operate at lower temperatures. They need far less fuel, and far less fission products build up as the fuel is used. On the other hand, their fuel requires more highly enriched uranium, typically up to 20% U-235, although some use 93 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neutron Source
A neutron source is any device that emits neutrons, irrespective of the mechanism used to produce the neutrons. Neutron sources are used in physics, engineering, medicine, nuclear weapons, petroleum exploration, biology, chemistry, and nuclear power. Neutron source variables include the energy of the neutrons emitted by the source, the rate of neutrons emitted by the source, the size of the source, the cost of owning and maintaining the source, and government regulations related to the source. Small devices Spontaneous fission Some isotopes undergo spontaneous fission (SF) with Neutron emission, emission of neutrons. The most common spontaneous fission source is the isotope californium-252. 252Cf and all other SF neutron sources are made by irradiating uranium or a Transuranium element, transuranic element in a nuclear reactor, where neutrons are absorbed in the starting material and its subsequent reaction products, transmuting the starting material into the SF isotope. 252Cf n ...

Heinz Maier-Leibnitz
Heinz Maier-Leibnitz (28 March 1911, in Esslingen am Neckar – 16 December 2000, in Allensbach) was a German physicist. He made contributions to nuclear spectroscopy, coincidence measurement techniques, radioactive tracers for biochemistry and medicine, and neutron optics. He was an influential educator and an advisor to the Federal Republic of Germany on nuclear programs. During World War II, Maier-Leibnitz worked at the Institute of Physics of the Kaiser Wilhelm Institute for Medical Research, in Heidelberg. After the war, he spent a year working in North America, after which he returned to the Institute of Physics. In 1952, he assumed the Chair for Technical Physics and directorship of the Laboratory for Technical Physics at the . He became a leader in establishing and building centers which used nuclear reactors as neutron sources for research. The first was the , which was the seed for the entire Garching research campus of the . The second was the German-French project to c ...

Garching
Garching bei München (, ''Garching near Munich'') or Garching is a city in Bavaria, near Munich. It is the home of several research institutes and university departments, located at Campus Garching. History Spatial urban planning Garching was small Bavarian village, until the Free State of Bavaria decided to implement a technology and urban planning policy whereby science should be clustered north of Munich. This urban planning policy was in line with the principles advanced by the International Congress of Modernist Architects (CIAM) in the 1933 Athens Charter. Garching was redeveloped in three spatially separated parts, to cover the urban functions of industry, habitation, and research. In 1959 a new residential quarter for Max Planck Society employees was constructed. In 1960 the Max Planck Institute for Plasma Physics was established in Garching. In 1963 Technical University of Munich (TUM) published plans, whereby some TUM institutes would be moved to Garching. The M ...

Neutron Facilities
The neutron is a subatomic particle, symbol or , that has no electric charge, and a mass slightly greater than that of a proton. The neutron was discovered by James Chadwick in 1932, leading to the discovery of nuclear fission in 1938, the first self-sustaining nuclear reactor (Chicago Pile-1, 1942) and the first nuclear weapon (Trinity, 1945). Neutrons are found, together with a similar number of protons in the nuclei of atoms. Atoms of a chemical element that differ only in neutron number are called isotopes. Free neutrons are produced copiously in nuclear fission and fusion. They are a primary contributor to the nucleosynthesis of chemical elements within stars through fission, fusion, and neutron capture processes. Neutron stars, formed from massive collapsing stars, consist of neutrons at the density of atomic nuclei but a total mass more than the Sun. Neutron properties and interactions are described by nuclear physics. Neutrons are not elementary particles; each is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
