emitted charge
1Charge contrast imaging — is an scanning electron microscope imaging mode which can produce images of otherwise invisible microstructures in insulating materials.[1] While the technique clearly illustrates changes in minerals which reflect genuine compositional… …
2Charge-coupled device — A specially developed CCD used for ultraviolet imaging in a wire bonded package. A charge coupled device (CCD) is a device for the movement of electrical charge, usually from within the device to an area where the charge can be manipulated, for… …
3Charge and discharge — Discharge Dis*charge , n. [Cf. F. d[ e]charge. See {Discharge}, v. t.] 1. The act of discharging; the act of relieving of a charge or load; removal of a load or burden; unloading; as, the discharge of a ship; discharge of a cargo. [1913 Webster]… …
4Space charge — is a concept in which excess electric charge is treated as a continuum of charge distributed over a region of space (either a volume or an area) rather than distinct point like charges. This model typically applies when charge carriers have been… …
5space charge — Elect. a distribution of an excess of electrons or ions over a three dimensional region, in contrast to the distribution of an electric charge over the surface of a conductor. [1910 15] * * * ▪ physics electrical charge distributed through… …
6Intensified charge-coupled device — An intensified charge coupled device (ICCD) is a CCD that is optically connected to an image intensifier, that is mounted in front of the CCD. An image intensifier includes three functional elements: a photocathode, a micro channel plate (MCP)… …
7Edinburgh congestion charge — The Edinburgh congestion charge (also known as Edinburgh road tolls) was a proposed scheme of congestion pricing for Scotland s capital city. It planned to reduce congestion by introducing a daily charge to enter a cordon within the inner city,… …
8Thermionic emission — Closeup of the filament on a low pressure mercury gas discharge lamp showing white thermionic emission mix coating on the central portion of the coil. Typically made of a mixture of barium, strontium and calcium oxides, the coating is sputtered… …
9electromagnetic radiation — Physics. radiation consisting of electromagnetic waves, including radio waves, infrared, visible light, ultraviolet, x rays, and gamma rays. [1950 55] * * * Energy propagated through free space or through a material medium in the form of… …
10radiation measurement — ▪ technology Introduction technique for detecting the intensity and characteristics of ionizing radiation, such as alpha, beta, and gamma rays or neutrons, for the purpose of measurement. The term ionizing radiation refers to those… …
