21Cherenkov radiation — glowing in the core of the Advanced Test Reactor …
22Čerenkov radiation — (also spelled Cerenkov or Cherenkov) is electromagnetic radiation emitted when a charged particle (such as an electron) passes through an insulator at a speed greater than the speed of light in that medium. The characteristic blue glow of nuclear …
23Magnetometer — A magnetometer is a measuring instrument used to measure the strength or direction of a magnetic field either produced in the laboratory or existing in nature. Some countries such as the USA, Canada and Australia classify the more sensitive… …
24Detection of internally reflected Cherenkov light — In particle physics experiments a Detection of Internally Reflected Cherenkov light (DIRC) detector measures the velocity of charged particles and is used for particle identification. It is a design of a Ring imaging Cherenkov detector where… …
25Technological applications of superconductivity — Some of the technological applications of superconductivity include: the production of sensitive magnetometers based on SQUIDs fast digital circuits (including those based on Josephson junctions and rapid single flux quantum technology), powerful …
26Image noise — Noise clearly visible in an image from a digital camera Image noise is random (not present in the object imaged) variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the… …
27Digital delay generator — A digital delay generator is a piece of electronic test equipment that provides precise delays for triggering, syncing, delaying and gating events. These generators are used in many types of experiments, controls and processes where electronic… …
28Shot noise — Photon noise simulation. Shot noise is a type of electronic noise that may be dominant when the finite number of particles that carry energy (such as electrons in an electronic circuit or photons in an optical device) is sufficiently small so… …
29spectroscopy — spectroscopist /spek tros keuh pist/, n. /spek tros keuh pee, spek treuh skoh pee/, n. the science that deals with the use of the spectroscope and with spectrum analysis. [1865 70; SPECTRO + SCOPY] * * * Branch of analysis devoted to identifying… …
30Mathematics and Physical Sciences — ▪ 2003 Introduction Mathematics Mathematics in 2002 was marked by two discoveries in number theory. The first may have practical implications; the second satisfied a 150 year old curiosity. Computer scientist Manindra Agrawal of the… …
