or cathode and scratched the surface with sandpaper to form a light panel capable of producing a large stable and homogenous emission current with low energy consumption.
Under a strong electric field the cathode emits tight high-speed beams of electrons through its sharp nanotube tips a phenomenon called field emission.
Field emission electron sources catch scientists'attention due to its ability to provide intense electron beams that are about a thousand times denser than conventional thermionic cathode (like filaments in an incandescent light bulb.
which is perpendicular to the axes of the wheels.""By checking the wheels'direction of rotation clockwise
It is exactly the same with the beams of light in the ultra-thin glass fibre.
Typically the interest of this type of emitter is to be able to emit a beam of ions
and not a beam of droplets says Herbert Shea an associate professor in the Microsystems for Space technologies Laboratory at the cole Polytechnique Fdrale de Lausanne.
Tests with the nanotube cathode have produced beam currents a thousand to a million times greater than the one generated with a large pricey laser system.
and expertise for handling intense electron beams one of relatively few labs that can support this project.
When a strong electric field is applied it pulls streams of electrons off the surface of the cathode creating the electron beam.
The electric and magnetic fields of the particle accelerator then organize the electrons into a beam. The tested nanotube cathode requires no laser:
Specifically Yamaguchi and his group used molecular beam epitaxy (MBE) to grow a layer of Inas QDS with a density of 5 x 1011 cm-2 on Gaassb/Gaas (100) substrates.

One beam arouses fluorescent molecules to glow while the second beam suppresses all other fluorescence except for that in a nanometer-sized area.

so that drivers can keep their high beams on even when other cars are coming toward them.
or snowflakes seem to disappear from its beam to clear the vision of the driver a trick that this team of engineers from Carnegie mellon University has been working on for a few years now.
The headlight is made actually up of not just one beam of light but one million tiny individual beams.
The individual beams are created the same way pixels on a projector are. There's a semiconductor chip that has an array of a million tiny mirrors on it.
This way the system can turn off some beams sometimes without the driver noticing too much. To make raindrops disappear the system tracks falling rain predicts where the drops are going
and then turns off the beams that would otherwise reflect light off the drops. To make headlights appear dimmer to oncoming drivers the system tracks other cars
and turns off only the beams that are aimed at those drivers. To make arrows on the road the beams project their light accordingly.
It's like having a football field full of dorky marching-band players that you can rearrange into whatever patterns you like.
