| electron acceptor | <chemistry> A molecule or compound that gets electrons during an oxidation-reduction reaction. (19 Jan 1998) |
|---|---|
| electron beam | <microscopy> A stream of electrons in an electron optical system. (05 Aug 1998) |
| electron capture | <radiobiology> Nuclear decay process whereby a proton in the nucleus absorbs an orbiting electron and converts to a neutron. (09 Oct 1997) |
| electron carrier | <chemistry> A protein which can either accept or donate electrons in oxidation-reduction reactions. (19 Jan 1998) |
| Electron Channeling Pattern | <microscopy> A pattern formed by the periodic backscattering of electrons by the specimen lattice in a transmission electron microscope. Allows determination of crystal structure and lattice parameters in crystals greater than 10 micrometres diameter. Acronym: ECP (05 Aug 1998) |
| electron cyclotron discharge cleaning | Using relatively low power microwaves (at the electron cyclotron frequency) to create a weakly ionised, essentially unconfined hydrogen plasma in the vacuum chamber. The ions react with impurities on the walls of the tokamak and help remove them from the chamber. For instance, Alcator C-mod typically applies electron cyclotron discharge cleaning for a few days prior to beginning a campaign, and a few hours before each day's run. (09 Oct 1997) |
| electron cyclotron emission | <physics, radiobiology> As electrons gyrate around in a magnetic field (see also larmor radius or cyclotron radius), they radiate radio-frequency electromagnetic waves. This is known as electron cyclotron emission, and can be measured to help diagnose a plasma. (09 Oct 1997) |
| electron cyclotron heating | <physics, radiobiology> Radiofrequency heating scheme that works by injecting electromagnetic wave energy at the electron cyclotron gyration frequency. The electric field of the electromagnetic wave at this frequency looks to a gyrating electron like a static electric field, and thus causes large acceleration of the electron (larger than if the frequency were off the cyclotron frequency and thus, to the electron, appearing to change direction as a function of time). The accelerated electron gains energy, which is then shared with other particles through collisions, resulting in heating. Higher harmonics (multiples) of the cyclotron frequency can also be used in principle. (09 Oct 1997) |
| electron diffraction | <technique> The phenomenon, or technique of producing diffraction patterns through the incidence of electrons upon matter. (05 Aug 1998) |
| electron donor | A molecule or compound that gives up electrons in an oxidation-reduction reaction. (09 Oct 1997) |
| electron gun | <apparatus> A cathode/anode device intended to produce a stream of electrons. Also used inside a video camera tube and monitor picture tube that contains a heated cathode. Electrons emitted by the gun are focused to produce the scanning beam. (05 Aug 1998) |
| electron image | <microscopy> A representation of an object formed by a beam of electrons focused by an electron optical system. (05 Aug 1998) |
| electron interferometer | An interferometer that employs an electron beam in place of a light beam. (05 Mar 2000) |
| electron interferometry | Interferometry in which a beam of electrons is used instead of a beam of light. (05 Mar 2000) |
| electron lens | <physics> A device for focusing an electron beam. (05 Aug 1998) |
