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 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 beam tomography — (EBT) is a specific form of computed axial tomography (CAT or CT) in which the X ray tube is not mechanically spun in order to rotate the source of X ray photons. This different design was explicitly developed to better image heart structures… … Wikipedia
Electron microprobe — An electron microprobe (EMP), also known as an electron probe microanalyser (EPMA) is an analytical tool used to non destructively determine the chemical composition of small volumes of solid materials. It works similarly to a scanning electron… … Wikipedia
electron tube — an electronic device that consists, typically, of a sealed glass bulb containing two or more electrodes: used to generate, amplify, and rectify electric oscillations and alternating currents. Also called electronic tube. Cf. gas tube, vacuum tube … Universalium
Electron — For other uses, see Electron (disambiguation). Electron Experiments with a Crookes tube first demonstrated the particle nature of electrons. In this illustration, the profile of the cross shaped target is projected against the tube face at right… … Wikipedia
