TL;DR: The Linac Coherent Light Source free-electron laser has achieved coherent X-ray generation down to a wavelength of 1.2 A and at a brightness that is nearly ten orders of magnitude higher than conventional synchrotrons.
Journal ArticleDOI

TL;DR: The SLAC MeV UED system operates at 120-Hz repetition rate with outstanding performance, including the reciprocal space resolution, temporal resolution, and machine stability.
Journal ArticleDOI

TL;DR: Very low-emittance measurements made at low bunch charge, and a few femtosecond bunch length produced by the LCLS bunch compressors, show the possibilities of generating hundreds of GW at 1.5 A x-ray wavelength and nearly a single longitudinally coherent spike at 2-fs duration.
Journal ArticleDOI

TL;DR: This analysis shows that the relative arrival time of the Ti:Sapphire laser and the x-ray pulses had a distribution with a standard deviation of approximately 120 fs, which suggests that simple technical improvements could reduce the jitter to better than 50 fs.
Journal ArticleDOI
Measurements of the linac coherent light source laser heater and its impact on the x-ray free-electron laser performance

TL;DR: In this article, a laser-heater system has been installed in the linac coherent light source (LCLS), which modulates the energy of a 135-MeV electron bunch with an IR-laser beam in a short undulator, enclosed within a four-dipole chicane.
