Compact X-Ray Free-Electron Laser

Short Wavelength Coherent Radiation: Generation and Applications, 1988
We present a design concept and simulation of the performance of a compact x-ray, free electron laser driven by ultra-high gradient rf-linacs. The accelerator design is based on recent advances in high gradient technology by a LLNL/SLAC/LBL collaboration† and on the development of bright, high current electron sources by BNL and LANL.

Microfluidic Mixing Injector Holder Enables Routine Structural Enzymology Measurements with Mix-and-Inject Serial Crystallography Using X-ray Free Electron Lasers.

Analytical Chemistry, 2019
The emerging technique of Mix-and-Inject Serial Crystallography (MISC) at X-ray free electron laser sources provides atomically detailed structural information about biomolecules as they function. Despite early successes, MISC is currently limited by the

Virus Structures by X-Ray Free-Electron Lasers

Annual Review of Virology, 2019
Until recently X-ray crystallography has been the standard technique for virus structure determinations. Available X-ray sources have continuously improved over the decades, leading to the realization of X-ray free-electron lasers (XFELs). They provide high-intensity femtosecond X-ray pulses, which allow for new kinds of experiments by making use of ...

Focusing mirror for x-ray free-electron lasers

Review of Scientific Instruments, 2008
We present the design, fabrication, and evaluation of a large total-reflection mirror for focusing x-ray free-electron laser beams to nanometer dimensions. We used an elliptical focusing mirror made of silicon that was 400mm long and had a focal length of 550mm.

Laser-pumped x-ray free electron laser

2008 IEEE 35th International Conference on Plasma Science, 2008
Ultrashort, high-brightness X-ray pulses are an important tool in many areas of research. In principle, a laser-pumped free-electron laser (FEL) can generate coherent, polarized X-ray for this purpose. In a laser-pumped X-ray FEL an intense laser field replaces the magnetic wiggler field of a conventional FEL.

Gas, Chemical, Free Electron, and X-Ray Lasers

1998
In this chapter, the most important types of lasers involving low density active media are considered, namely gas, chemical and free electron lasers. Some considerations on X-ray lasers involving highly ionized plasmas will also be presented. The main emphasis, again, is to stress the physical behavior of the laser and to relate this behavior to the ...

VUV and X-ray free-electron lasers

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2001
Abstract Recent advances in linear accelerators, new developments in laser driven low-emittance electron guns, and the feasibility of ultra-precise long undulators open up the exciting possibility of building single pass Free-Electron Lasers (FELs) based on self-amplified spontaneous emission (SASE).

Next-Generation X-Ray Free-Electron Lasers

IEEE Journal of Selected Topics in Quantum Electronics, 2012
Research frontiers for future free-electron lasers are discussed. Attention is given to ideas for improving the temporal coherence and obtaining subfemtosecond X-ray pulses. Improving brightness of the electron bunches is considered to be a major step forward for an electron beam accelerator simultaneously supporting multiple free-electron laser lines.
