TL;DR: The Linac Coherent Light Source (LCLS) as mentioned in this paper is a free-electron-laser (FEL) R&D facility operating in the wavelength range 1.5-15 angstrom, which utilizes the SLAC linac and produces sub-picosecond pulses of short wavelength x-rays with very high peak brightness and full transverse coherence.

TL;DR: In this paper, the authors report on a research and development program underway and in planning at SLAC for addressing critical questions in these areas, including the construction and operation of a linac test stand for developing laser-driven photocathode rf guns with normalized emittances approaching 1 mm-mrad, development of advanced beam compression, stability, and emittance control techniques at multi-GeV energies, and the development of X-ray optics and instrumentation for extracting, modulating, and delivering photons to experimental users.

TL;DR: In this paper, the design and R&D status of the X-ray optics section of the SLAC Linac Coherent Light Source (LCLS), a 1.5-Angstrom self-amplified spontaneous emission (SASE) FEL driven by the last kilometer of SLAC 3-kilometer S-band linac, is summarized.

TL;DR: In this paper, the Stanford Linear Accelerator (SLA) was used to drive a linac coherent light source (LCLS) operating at hard x-ray wavelengths, which achieved a high energy, extremely bright electron beam through an undulator, without the optical cavity resonator normally used in storage ring-based freeelectron lasers.

TL;DR: Pellegrini et al. as discussed by the authors proposed a linac coherent light source (LCLS) using the SLAC linac at wavelengths from about 3 to 100 nm and possibly even shorter wavelengths in the future.
