SEMINAR      Tuesday, 14th September 2004 - h. 14:30  Auditorium B. Touschek     C. Pellegrini (UCLA) STATUS OF LCLS PROJECT Abstract The Linac Coherent Light Source (LCLS) will be the world's first x-ray free electron laser when it becomes operational in 2009. LCLS is currently in the detailed project engineering and design phase, with a construction start planned in FY2005.    Pulses of x-ray laser light from LCLS will be many orders of magnitude brighter and several orders of magnitude shorter than what can be produced by any other x-ray source available now or in the near future.    These characteristics will enable frontier new science in areas that include discovering and probing new states of matter, understanding and following chemical reactions and biological processes in real time, imaging chemical and structural properties of materials on the nanoscale, and imaging non-crystalline biological materials at atomic resolution.
