Free electron lasers are now being designed which will operate at wavelengths down to about 1 Å. These machines, which rely on high-energy electron accelerator technology, are often referred to as the fourth generation in the development of sources of synchrotron radiation. Due to the physics of the high-gain, single-pass FEL process, the radiation produced will have unique properties. In particular:

These source properties so exceed those of any existing x-ray source that predicting the applications of an x-ray FEL is not an easy task. Several workshops over the last 8 years have addressed this issue [1-4] and many possible applications have been discussed, but as yet there is no clear consensus as to which will be most scientifically rewarding. This latest workshop was convened to provide an opportunity for participants to study in depth the applications of the proposed LCLS free electron laser x-ray source in several scientific fields. A design study has been carried out for this source [5], providing detailed calculations of the expected characteristics of the FEL radiation and the experimental environment. The fields chosen for examination at this workshop were closely related, inviting cross-fertilization of ideas. The goal of the workshop was to help clarify the most exciting applications of the LCLS, and the necessary scientific development path toward realizing these applications.

More than ?? participants attended, from ?? countries. The workshop structure included invited plenary talks on the state of the art of several relevant x-ray techniques, tutorial talks on the LCLS and its radiation, and working group sessions focused around four characteristics of the LCLS radiation: its high peak power, high spatial coherence, high degeneracy, and very short pulse length. These working groups each produced a report at the end of the workshop.

A strong effort was made throughout the workshop to use realistic, conservative source parameters. Members of the LCLS design study team participated in all of the working group sections, giving a very productive, close interaction between applications scientists and source designers.

Included in this online version of the proceedings are the four working group reports.
