Neutron interferometer — In physics, a neutron interferometer is an interferometer capable of diffracting neutrons, allowing the wave like nature of neutrons, and other related phenomena, to be explored. Interferometry inherently depends on the wave nature of the object … Wikipedia
Neutron detection — is the effective detection of neutrons entering a well positioned detector. There are two key aspects to effective neutron detection: hardware and software. Detection hardware refers to the kind of neutron detector used (the most common today is… … Wikipedia
Neutron Reflectometry — is a laboratory technique for measuring the structure of thin films, similar to the often complementary techniques of X ray reflectivity and ellipsometry. The technique provides valuable information over a wide variety of scientific and… … Wikipedia
Neutron — Représentation schématique de la composition en quarks d un neutron, avec deux quarks d et un quark u. L interaction forte est transmise par des gluons (représentés ici par un tracé sinusoïdal). La couleur des quarks fait référence aux trois… … Wikipédia en Français
Neutron tomography — is a form of computed tomography involving the production of three dimensional images by the detection of the absorbance of neutrons produced by a neutron source.[1] It created a three dimensional image of an object by combining multiple planar… … Wikipedia

Nv (neutron flux) — The symbol nv is commonly used to designate a flux of thermal neutrons equal to one thermal neutron per square centimeter per second. The symbol is used primarily to quantify the sensitivity of neutron detectors which are commonly described as… … Wikipedia
Startup neutron source — RBMK reactor control rod positions at the moment of the Chernobyl disaster; blue=startup neutron sources (12), yellow=shortened control rods from the reactor bottom (32), grey=pressure tubes (1661), green=control rods (167), red=automatic control … Wikipedia
Crystal monochromator — Neutron monochromator for the ECHIDNA powder diffractometer at OPAL in Australia. It is made by slabs of [113] oriented Germanium crystals which are inclined towards each other in order to focus down the Bragg reflected beam. A crystal… … Wikipedia
Collimator — Example of a particle collimator A collimator is a device that narrows a beam of particles or waves. To narrow can mean either to cause the directions of motion to become more aligned in a specific direction (i.e., collimated or parallel) or to… … Wikipedia
