Garching
Garching bei München (''Garching near Munich'') or Garching is a town in Bavaria, Germany, near Munich. It is the home of several research institutes and university departments on its campus. It became a city on 14 September 1990. Location The town is at , near the river Isar and the Bundesautobahn 9. Garching has a number of scientific research institutes and scientific experiment facilities located in the city, including a linear accelerator and a research nuclear reactor. The nuclear research reactor, nicknamed ''Atomei'' (atomic egg) appears in the city's coat of arms, and started the process leading to an accumulation of research institutes. A number of roads and places in the city are named after scientists, mathematicians and technical innovators such as Carl von Linde, Rudolf Diesel, Albert Einstein, Leonhard Euler, Werner Heisenberg, Max Planck, Wilhelm Röntgen, and Erwin Schrödinger. Districts The town has four districts: * Garching * Dirnismaning * Hochbrück * H ...

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 ...

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 (SF) Some isotopes undergo SF with 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 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 neutron sources are typically 1/4" to 1/2" in diameter an ...

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 co ...
