WASHINGTON, D.C., October 9, 2018 -- One of the most enduring "Holy Grail" experiments in science has been attempts to directly observe atomic motions during structural changes. This prospect ...

Ultrashort electron beams with narrow energy spread, high charge and low jitter are essential for ultrafast electron diffraction experiments to resolve phase transitions in metals, semiconductors ...

The research team used tiny nanopillars of germanium wire as stand-ins for the tips of electron guns in experiments aimed at improving electron emission. This image was made with a scanning electron ...

It is no secret that the quantum world is weird. Consider a setup in which an electron gun fires the subatomic particles at a screen, as in the classic “double-slit experiment” [see graphic ...
