With intensities 108–1010 times greater than other laboratory sources, X-ray free-electron lasers are currently opening up new frontiers across many areas of science. In this Review we describe how these unconventional lasers work, discuss the range of new sources being developed worldwide, and ...
The first decade of X-ray free-electron lasers (XFELs) has led to technological advances and scientific discoveries, but has also highlighted several facility-level challenges. Chi-Chang Kao, Director of SLAC, discusses the lessons to be learned from the first 10 years of operation and shares ...
We report the start-to-end modeling of our accelerator lattice design employing a laser-assisted bunch compression (LABC) scheme in an X-ray free electron laser (XFEL), using the proposed Matter-Radiation Interactions in Extremes (MaRIE) XFEL parameters. The accelerator lattice utilized a two-st...
Use X-Ray to explore cast information like actor bios, photos, filmographies, and character backstories. I know I've heard that song before, but where? X-Ray can show you the name of the song and who sings it. How can I share this fight scene with my Nanna?
Activities on free-electron laser (FEL) X-ray sources, based on linear accelerators, to produce spatially coherent, ultra-short (∼100 fs) pulses with very high peak brilliance (1028–1032 photons/s/mm2/mrad2/0.1% BW) are summarized, with special emphasis on the European XFEL project in ...

Polarization control of an X-ray free-electron laser with a diamond phase retarder A diamond phase retarder was applied to control the polarization states of a hard X-ray free-electron laser (XFEL) in the photon energy range 5鈥 20keV. The... M Suzuki,Y Inubushi,M Yabashi,... - 《...
FLASH (Free-Electron Laser in Hamburg) was the first free-electron laser in the XUV/soft X-ray spectral range and officially started operation as a user facility in summer 2005. In pulses of about 50 fs duration it provides as many photons as one gets in 1 s from modern storage ring ...
In the regime of extremely short wavelengths, X-ray free-electron lasers (XFELs) with exceptional peak brilliance have unveiled crucial details about the structures, dynamics and physics of various materials. Although X-ray focusing optics to enhance the intensity have progressed, achieving a single...
diagnosed using X-ray free electron laser diffraction. We found that the initial compression state caused by the femtosecond laser-driven shock wave is the same as that caused by conventional shock waves. We also found, for the first time experimentally, the temporal deviation of peaks of stress...
