Sentences with phrase «focused electron pulses»

A second point was the finding that textures can be written with much lower beam intensity using tightly focused electron pulses.

Not exact matches

The researchers in Erlangen and Jena have now achieved this by focusing laser pulses onto a nanometre - sharp metal tip, causing the tip to emit electrons.

The scientists used the free - electron laser LCLS at the SLAC National Accelerator Laboratory in the U.S., and employed optics to focus each X-ray pulse to a similar size as one of the virus particles.

Varga's research focuses on the interaction of lasers and matter at the atomic scale and is part of the new field of attosecond science — an attosecond is a billion billionths of a second — that is allowing scientists to study extremely short - lived phenomena such as the making and breaking of chemical bonds and tracking the real - time motion of electrons within semiconductors by probing them with attosecond pulses of laser light.

These pulses carry energies of three MeV (three million electron volts), focused to a spot one millimeter in diameter.

These opportunities include the use of short - pulsed X-ray sources for extracting time - dependent structural information from proteins; and the revolutionary new possibilities created by X-ray Free Electron Lasers, which combine ultrafast X-ray pulses with high brilliance focussing capabilities to create an entirely new regime of pre-damage time - resolved serial femtosecond crystallography on unprecedented time - scales.
