Beam-like
41Bonnor beam — In general relativity, the Bonnor beam is an exact solution which models an infinitely long, straight beam of light. It is an explicit example of a pp wave spacetime.The Bonnor beam is obtained by matching together two regions:* a uniform plane… …
42Neutral Beam Injection — In order to initiate a sustained fusion reaction, it is usually necessary to use many methods to heat the plasma, including RF heating, electron cyclotron resonance heating (ECRH), ion cyclotron resonance heating (ICRH), and neutral beam… …
43Gas cluster ion beam — Gas Cluster Ion Beams (GCIB) is a new technology for nano scale modification of surfaces. It can smooth a wide variety of surface material types to within an angstrom of roughness without subsurface damage. It is also used to chemically alter… …
44Electron Beam Melting — (EBM) is a type of rapid prototyping for metal parts. It is often classified as a rapid manufacturing method. The technology manufactures parts by melting metal powder layer per layer with an electron beam in a high vacuum. Unlike some metal… …
45Pencil beam — A pencil beam is a beam of radiant energy in the form of a narrow cone or cylinder.Antennas which strongly bundle in azimuth and elevation are often described as a pencil beam antenna. For example the phased array antenna can send out a beam thin …
46Autofocus assist beam — An Autofocus assist beam or AF assist beam is a lamp (usually red) which is incorporated into photographic cameras and flash units. This beam usually projects a regular pattern on to the subject which is recognized by the camera s AF system and… …
47off the beam — {adv.} or {adj. phr.} 1. (Of an airplane) Not in the radio beam that marks the path to follow between airports; flying in the wrong direction. * /A radio signal tells the pilot of an airplane when his plane is off the beam./ 2. {slang} Wrong;… …
48off the beam — {adv.} or {adj. phr.} 1. (Of an airplane) Not in the radio beam that marks the path to follow between airports; flying in the wrong direction. * /A radio signal tells the pilot of an airplane when his plane is off the beam./ 2. {slang} Wrong;… …
49Ion beam assisted deposition — or IBAD or IAD (not to be confused with ion beam induced deposition, IBID) is a materials engineering technique which combines ion implantation with simultaneous sputtering or another physical vapor deposition technique. Besides providing… …
50Radioactive Ion Beam Optimization — RIBO stands for the Radioactive Ion Beam Optimization, a concept closely linked to the extraction of rare isotopes from targets.OverviewIndeed, rare and radioactive here are synonyms. These are nuclei with an excess or deficit of neutrons or… …
