<p class="MsoNormal">Large synchrotrons, and now free
electron lasers, are the most powerful sources of x-ray beams. Through increasingly advanced
imaging, diffraction, and
spectroscopic techniques, physicists, chemists, biologists, and medical doctors, as
well as quality-control inspectors, airline
passenger screeners, and forensic scientists have resolved the structural detail and elemental
constituency on length scales from inter-atomic
spacing to the size of the human body. However
these x-ray <o:p></o:p></p>
<p class="MsoNormal">sources have grown enormous in
size and cost, reaching $1 billion. We are pursuing an alternative approach,
in which the traditional magnets used
to produce x-rays are replaced with high power laser beams, reducing the size and cost of the
accelerator by a factor of 100. By
combining the high power lasers with a small superconducting linac, x-ray beams with performance rivaling,
and in some parameters surpassing,
the large facilities are possible. This
presentation describes the
physics and technology of the innovative new lasers and accelerators under development, and
the science that they enable.<o:p></o:p></p>
