Particle identification — is the process of using information left by a particle passing through a particle detector to identify the type of particle. Particle identification reduces backgrounds and improves measurement resolutions, and is essential to many analyses at… … Wikipedia
Particle radiation — is the radiation of energy by means of fast moving subatomic particles. Particle radiation is referred to as a particle beam if the particles are all moving in the same direction, similar to a light beam.Due to the wave particle duality, all… … Wikipedia
Particle image velocimetry — (PIV) is an optical method used to measure velocities and related properties in fluids. The fluid is seeded with particles which, for the purposes of PIV, are generally assumed to faithfully follow the flow dynamics. It is the motion of these… … Wikipedia
Particle-induced X-ray emission — or proton induced X ray emission (PIXE) is a technique used in the determining of the elemental make up of a material or sample. When a material is exposed to an ion beam, atomic interactions occur that give off EM radiation of wavelengths in the … Wikipedia

particle accelerator — accelerator (def. 7). [1945 50] * * * Device that accelerates a beam of fast moving, electrically charged atoms (ions) or subatomic particles. Accelerators are used to study the structure of atomic nuclei (see atom) and the nature of subatomic… … Universalium
Particle counter — A particle counter is an instrument that detects and counts particles. Applications of particle counters are separated into two primary categories:*Aerosol particle counters *Liquid particle countersAerosol particle countersAerosol Particle… … Wikipedia
Particle size distribution — The particle size distribution [Jillavenkatesa A, Dapkunas S J, Lin Sien Lum, Particle Size Characterization , NIST Special Publication 960 1, 2001] (PSD) of a powder, or granular material, or particles dispersed in fluid, is a list of values or… … Wikipedia
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
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
