Spallation Neutron Source
The Spallation Neutron Source (SNS) is an accelerator-based neutron source facility in the U.S. that provides the most intense pulsed neutron beams in the world for scientific research and industrial development.In 2007, SNS was entered into thGuinness Book of World Recordsas the most powerful pulsed spallation source. Each year, this facility hosts hundreds of researchers from universities, national laboratories, and industry, who conduct basic and applied research and technology development using neutrons. SNS is part of Oak Ridge National Laboratory, which is managed by UT-Battelle for the United States Department of Energy (DOE). SNS is a DOE Office of Science user facility, and it is open to scientists and researchers from all over the world. Neutron scattering research Neutron scattering allows scientists to count scattered neutrons, measure their energies and the angles at which they scatter, and map their final positions. This information can reveal the molecular and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spallation is a process in which fragments of material (spall) are ejected from a body due to impact or stress. In the context of impact (mechanics), impact mechanics it describes ejection of material from a target during impact by a projectile. In Planetary science, planetary physics, spallation describes meteoritic impacts on a planetary surface and the effects of stellar winds and cosmic rays on Atmosphere, planetary atmospheres and Planetary surface, surfaces. In the context of mining or geology, spallation can refer to pieces of rock breaking off a rock face due to the internal stresses in the rock; it commonly occurs on shaft mining, mine shaft walls. In the context of anthropology, spallation is a process used to make stone tools such as arrowheads by knapping. In nuclear physics, spallation is the process in which a heavy nucleus emits numerous nucleons as a result of being hit by a high-energy subatomic particle, particle, thus greatly reducing its atomic weight.
