X-ray free-electron lasers (x-ray FELs) give us for the first time the possibility to explore
structures and dynamical processes of atomic and molecular systems at the angstrom …

X-ray free-electron lasers (FELs) are state-of-the-art scientific tools capable to study matter
on the scale of atomic processes. Since the initial operation of X-ray FELs more than a …

A simple method for generating single-spike hard x-ray pulses in free-electron lasers (FELs)
has been developed at the Linac Coherent Light Source (LCLS). This is realized by …

In the field of beam physics, two frontier topics have taken center stage due to their potential
to enable new approaches to discovery in a wide swath of science. These areas are …

This review is focused on free-electron lasers (FELs) in the hard to soft x-ray regime. The
aim is to provide newcomers to the area with insights into: the basic physics of FELs, the …

Ultrabrilliant, femtosecond X-ray pulses from X-ray free-electron lasers (XFELs) have
promoted the investigation of exotic interactions between intense X-rays and matters, and …

Accelerator-based light sources such as storage rings and free-electron lasers use
relativistic electron beams to produce intense radiation over a wide spectral range for …

Attosecond pulses are central to the investigation of valence-and core-electron dynamics on
their natural timescales,–. The reproducible generation and characterization of attosecond …

The interaction of high-power lasers with matter can generate Terahertz radiations that
efficiently contribute to THz Time-Domain Spectroscopy and also would replace X-rays in …
