Linac Coherent Light Source (LCLS) SLAC National Accelerator Laboratory The Linac Coherent Light Source (LCLS), the world's first hard X-ray free-electron laser, will start operation in summer 2009. LCLS will produce intense, sub-picosecond pulses of spatially-coherent X-rays. In a flash of about 100 femtoseconds duration, LCLS will provide 1012 X-ray photons, roughly as many photons as obtained in one second at today's best storage-ring-based synchrotron radiation facilities. LCLS X-rays will enable investigation of systems at the atomic and nano-scale under conditions where the matter is far from equilibrium, and actually undergoing real-time reactions. The international research community is invited to submit proposals to conduct experiments utilizing the unique capabilities of LCLS. Five experimental stations are currently being constructed: 1. Atomic, molecular and optical science (AMO); 2. Investigation of materials with soft X-rays (SXR); 3. Diffraction studies of stimulated dynamics (XPP); 4. Coherent imaging of non-periodic objects (CXI); and 5. Coherent scattering of nano-scale fluctuations (XCS). The soft-X-ray experimental stations, AMO and SXR, will be operational first in 2009-2010. The available spectral range will be from 0.8 to 2 keV, and the maximum repetition rate of the X-ray flashes is expected to be 60 Hz.
