Stopping power (particle radiation) — In passing through matter, fast charged particles ionize the atoms or molecules which they encounter. Thus, the fast particles gradually lose energy in many small steps. Stopping power is defined as the average energy loss of the particle per… … Wikipedia
Collision cascade — A classical molecular dynamics computer simulation of a collision cascade in Au induced by a 10 keV Au self recoil. This is a typical case of a collision cascade in the heat spike regime. Each small sphere illustrates the position of an atom, in… … Wikipedia

Rutherford backscattering spectroscopy — Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science. Sometimes referred to as high energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by… … Wikipedia
Range (particle radiation) — In passing through matter, charged particles ionize and thus lose energy in many steps, until their energy is (almost) zero. The distance to this point is called the range of the particle. The range depends on the type of particle, on its initial … Wikipedia
Threshold displacement energy — The threshold displacement energy Td is the minimum kinetic energy that an atom in a solid needs to be permanently displaced from its lattice site to a defect position. It is also known as displacement threshold energy or just displacement energy … Wikipedia
Precrash system — A precrash system is an automobile safety system designed to reduce the severity of an accident. Also known as forward collision warning systems they use radar and sometimes laser sensors to detect an imminent crash. Depending on the system they… … Wikipedia
Sputtering — is a process whereby atoms are ejected from a solid target material due to bombardment of the target by energetic ions. It is commonly used for thin film deposition, etching and analytical techniques (see below). Physics of sputtering Physical… … Wikipedia
