Since the discovery of electron-wave duality, electron scattering instrumentation has
developed into a powerful array of techniques for revealing the atomic structure of matter …

One of the great dream experiments in Science is to directly observe atomic motions as they
occur. Femtosecond electron diffraction provided the first'light'of sufficient intensity to …

Advances in attosecond spectroscopy have enabled tracing and controlling the electron
motion dynamics in matter, although they have yielded insufficient information about the …

With the recent advances in ultrabright electron and x-ray sources, it is now possible to
extend crystallography to the femtosecond time domain to literally light up atomic motions …

We used 600-femtosecond electron pulses to study the structural evolution of aluminum as it
underwent an ultrafast laser–induced solid-liquid phase transition. Real-time observations …

Electron imaging in space and time is achieved in microscopy with timed (near relativistic)
electron packets of picometer wavelength coincident with light pulses of femtosecond …

While correlated electrons are at the heart of many phenomena in condensed matter, as well
as atomic and molecular physics, Coulomb interactions in free-electron beams are generally …

The use of pump-probe experiments to study complex transient events has been an area of
significant interest in materials science, biology, and chemistry. While the emphasis has …

One of the grand challenges in chemistry has been to directly observe atomic motions
during chemical processes. The depiction of the nuclear configurations in space-time to …

We present a method for producing sub-100 fs electron bunches that are suitable for single-
shot ultrafast electron diffraction experiments in the 100 keV energy range. A combination of …
