Sentences with phrase «intense electron pulses»

Not exact matches

When an intense laser pulse strikes a plasma of electrons and positive ions, it shoves the lighter electrons forward, separating the charges and creating a secondary electric field that pulls the ions along behind the light like water in the wake of a speedboat.
As each flash is intense enough to completely ionise a neon atom and release an electron, the researchers could use those electrons like a flashgun, to illuminate some of the original 2.5 femtosecond trigger pulses of laser light.
Intense extreme ultraviolet FEL pulses were directed at the clusters and the resultant energy distribution of electrons knocked out of the clusters was measured using a «velocity map imaging spectrometer».
Since the FEL pulse is so intense, many electrons become loosely bound in the clusters at the same time; meaning many atoms become excited.
The investigation of cluster explosion dynamics under intense extreme - ultraviolet (XUV) pulses has so far been limited to large scale facilities like free - electron lasers.
This strategy makes use of the intense electric fields associated with pulsed, high - energy laser beams to accelerate electrons and protons to «relativistic» velocities (i.e. speeds approaching that of light).
These accelerators work by shooting pulses of intense laser light into plasma to create a wave rippling through the cloud of ionised gas, leaving a wake of electrons akin to those that form behind a speedboat in water.
Porous silicon has been made to glow under many types of excitation, including X-rays, intense pulses of infrared photons, and electron and ion beams.
Late last year two groups published papers in Science showing how intense laser pulses could be used to liberate electrons not only from the highest molecular orbital but also from the next orbital below.
«The work shows how magnetization of nanoscale magnets can be steered by intense ultrashort electron pulses,» said Alexander Schäffer, a doctoral student at Martin - Luther - Universität Halle - Wittenberg in Halle, Germany, and lead author of the paper.
