Electron beam welding — (EBW) is a fusion welding process in which a beam of high velocity electrons is applied to the materials being joined. The workpieces melt as the kinetic energy of the electrons is transformed into heat upon impact, and the filler metal, if used … Wikipedia
Electron degeneracy pressure — is a consequence of the Pauli exclusion principle, which states that two fermions cannot occupy the same quantum state at the same time. The force provided by this pressure sets a limit on how much matter can be squeezed together without it… … Wikipedia
Electron beam induced deposition — (EBID) is a process of decomposing gaseous molecules by electron beam leading to deposition of non volatile fragments onto a nearby substrate. Process Focused electron beam of scanning electron microscope (SEM) or scanning transmission electron… … Wikipedia
Electron cyclotron resonance — is a phenomenon observed both in plasma physics and condensed matter physics. An electron in a static and uniform magnetic field will move in a circle due to the Lorentz force. The circular motion may be superimposed with a uniform axial motion,… … Wikipedia
Electron beam physical vapor deposition — or EBPVD is a form of physical vapor deposition in which a target anode is bombarded with an electron beam given off by a charged tungsten filament under high vacuum. The electron beam causes atoms from the target to transform into the gaseous… … Wikipedia
Electron beam ion trap — (or its acronym EBIT) is used in physics to denote an electromagnetic bottle that produces and confines highly charged ions. It was invented by R. Marrs [Levine et al, 1988] and M. Levine at LLNL.An EBIT uses an electron beam focused by means of… … Wikipedia
Electron beam processing — involves irradiation of products using a high energy electron beam accelerator. Electron beam accelerators utilize an on off technology, with a common design being similar to that of a cathode ray television.Electron beam processing is used in… … Wikipedia
Electron energy loss spectroscopy — In electron energy loss spectroscopy (EELS) a material is exposed to a beam of electrons with a known, narrow range of kinetic energies. Some of the electrons will undergo inelastic scattering, which means that they lose energy and have their… … Wikipedia
Pressure measurement — The construction of a bourdon tube gauge, construction elements are made of brass Many techniques have been developed for the measurement of pressure and vacuum. Instruments used to measure pressure are called pressure gauges or vacuum gauges. A… … Wikipedia
Electron bubble — An electron bubble is the empty space created around a free electron in a cryogenic gas or liquid, such as neon or helium. They are typically very small, about 2 nm in diameter at atmospheric pressure.Electron bubbles in heliumAt room temperature … Wikipedia
