A new analysis reveals what happens when very short or narrow electron beams encounter a particle. The research is published ...

Physicists have proposed a way to extract the internal quantum states of electron wave packets by analyzing how those packets ...

FELs require a bright and stable source of high-energy electron bunches, so today’s facilities are driven by large and ...

Electron beam oscillators utilising surface wave structures represent a key technology in the generation of high‐power electromagnetic radiation. By deploying relativistic electron beams in ...

(Nanowerk News) Imagine standing by a lake and throwing a stone into the water. Waves spread out in circular patterns and can reflect at obstacles and boundaries. Researchers at the University of ...

Scientists at the X-ray free-electron laser SwissFEL have realized a long-pursued experimental goal in physics: to show how electrons dance together. The technique, known as X-ray four-wave mixing, ...

Electron beams (cyan haze in top left) are routinely used to determine the molecular structures of biomolecules in ...

A beam of electrons crossed just a few millimeters of plasma, then helped trigger an effect that usually belongs to massive ...

(Nanowerk News) One of the most fundamental interactions in physics is that of electrons and light. In an experiment at Goethe University Frankfurt, scientists have now managed to observe what is ...

Scientists at the University of Konstanz in Germany have advanced ultrafast electron microscopy to unprecedented time resolution. Reporting in Science Advances, the research team presents a method for ...

Superradiance When multiple electrons emit light in a coordinated manner, the resulting emission is much stronger than the sum of individual emissions. (Courtesy ...
