Beam

Knife-edge width Before the advent of the CCD beam profiler, the beam width was estimated using the knife-edge technique: slice a laser beam with a razor and measure the power of the clipped beam as a function of the razor position.

The beam divergence of an electromagnetic beam is an angular measure of the increase in beam diameter or radius with distance from the optical aperture or antenna aperture from which the electromagnetic beam emerges.

She’s reset her career-high beam scores at least thrice this season, she won the beam event title at Southern Utah with a score of 9.9, and is tied with Burleson for the team-best beam score this season – a 9.925.

A beam reach is with the wind at right angles to the boat, a close reach is anywhere between beating and a beam reach, and a broad reach is between a beam reach and running.

A laser beam (laser writer) or a beam of electrons (e-beam writer) is used to expose the pattern defined by the data file and travels over the surface of the substrate in either a vector or raster scan manner.

Beam fusion: A beam of high energy particles can be fired at another beam or target and fusion will occur.

Beam power tubes 6L6 tubes in glass envelopes main The beam power tube is usually a tetrode with the addition of beam-forming electrodes, which take the place of the suppressor grid.

Neutral Particle Beam In July 1989, the Beam Experiments Aboard a Rocket (BEAR) program launched a sounding rocket containing a neutral particle beam (NPB) accelerator.

Propagation of a laser beam The way in which the beam profile of a laser beam changes as it propagates is determined by diffraction.

The beam width can be measured in units of length at a particular plane perpendicular to the beam axis, but it can also refer to the angular width, which is the angle subtended by the beam at the source.

These may include pressor beams (a stronger pressor beam will counteract a weaker tractor beam) or plane shears aka shearing planes (a device to "cut" the tractor beam and render it ineffective).

While neutral beam injection is used primarily for plasma heating, it can also be used as a diagnostic tool and in feedback control by making a pulsed beam consisting of a string of brief 2-10 ms beam blips.

Press yes and as soon as you press yes you will be able to see either a Red beam of light or a Purple beam of light.

Researchers led by Columbia Engineering Professor Michal Lipson have developed a low-power beam steering platform that is a non-mechanical, robust, and scalable approach to beam steering.

Albert Baladi, the top executive at Beam Suntory, which owns the Jim Beam brand, says the donation is an investment in bourbon’s future.

Beam has a market cap of $9.00 million and $4.59 million worth of Beam was traded on exchanges in the last day.

In ADB mode, when another car is detected, the high beam is shaped in a way that prevents glare to active vehicles by dimming individual LEDs in the high beam LED array headlamp.

Markfield Beam Engine Museum is open to the public today, offering a chance to see inside the Grade 2 listed engine hall, and witness an 1888 restored steam-powered beam engine in action.

Additional beam options include optics with a 10˚ spot, 38˚ narrow flood, 60˚ flood, and 90˚ wide flood beam spreads.

A San Francisco official says a new $2 billion transit terminal that shut down over a cracked support beam has a second adjacent beam that also shows signs of cracking.
