Sentences with phrase «wavelength electron beam»

Not exact matches

Instead, the researchers shot in a beam of electrons to generate light of all wavelengths within the waveguide and measured the light leaking out of it.
But a laser can set up a quantum - mechanical interference that blocks the electrons from making the jump, allowing a second beam at the normally absorbed wavelength to zip through.
Neil's machine produces coherent laser light directly from an electron beam, allowing it to create any wavelength of light — in other words, any color on the spectrum.
An electron beam can be manipulated with magnets to produce a beam of any wavelength.
The sharp acceleration turns the traveling electron wave into a plane wave, like a nice regular pulse of an electron beam with an extremely short wavelength — exactly the kind of beam useful for imaging.
With much shorter wavelengths than photons of visible light, electron beams can be used to observe objects hundreds of times smaller than those that can be resolved with an optical microscope.
Single - grain major and minor element compositions were measured using electron microprobe wavelength dispersive spectrometry at the University of Oxford Research Laboratory for Archaeology and the History of Art, using a Jeol JXA8600 electron microprobe, in wavelength dispersive mode, with 15 - keV accelerating voltage, 6 - nA beam current, and 10 - μm defocused beam.
