the beam of electrons
61cathode-ray oscilloscope — ▪ instrument electronic display device containing a cathode ray tube (CRT) that generates an electron beam that is used to produce visible patterns, or graphs, on a phosphorescent screen. The graphs plot the relationships between two or… …
62electron microscope — n. an instrument that focuses a beam of electrons on an object, using electric or magnetic fields, to form an enlarged image of the object on a fluorescent screen, photographic plate, or cathode ray tube; specif., such an instrument in which the… …
63Williams , Robley Cook — (1908–) American biophysicist Williams, who was born in Santa Rosa, California, received a PhD in physics from Cornell University in 1935 and then went on to teach astronomy at the University of Michigan, transferring to the physics department in …
64CRT — An acronym for Cathode Ray Tube. This is the device which physically displays the information produced by the computer. It uses an electron gun to emit a stream of electrons into a vacuum. The beam of electrons strikes a layer of phosphor which …
65deflection — /di flek sheuhn/, n. 1. the act or state of deflecting or the state of being deflected. 2. amount of deviation. 3. the deviation of the indicator of an instrument from the position taken as zero. 4. Optics. deviation (def. 5a). 5. Mil. the angle… …
66Atom — The atom is the smallest unit of an element that retains the chemical properties of that element. An atom has an electron cloud consisting of negatively charged electrons surrounding a dense nucleus. The nucleus contains positively charged… …
67Electron-Cloud Effect — The Electron Cloud Effect (ECE) is a phenomenon associated with particle accelerators. Explanation Electron clouds are created when accelerated charged particles disturb stray electrons already floating in the tube, and bounce or slingshot the… …
68materials science — the study of the characteristics and uses of various materials, as glass, plastics, and metals. [1960 65] * * * Study of the properties of solid materials and how those properties are determined by the material s composition and structure, both… …
69Photoelectric effect — The photoelectric effect is a quantum electronic phenomenon in which electrons are emitted from matter after the absorption of energy from electromagnetic radiation such as x rays or visible light.cite book | title = Physics for Scientists… …
70HiPER — The High Power laser Energy Research facility (HiPER), is an experimental laser driven inertial confinement fusion (ICF) device undergoing preliminary design for possible construction in the European Union starting around 2010. HiPER is the first …
