"A Proposed NSF Science and Technology Center to build a compact ultra-bright x-ray (CUBIX) source"

Dr. William Graves
Massachusetts Institute of Technology


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
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.





Presentation: Physical Sciences Building II 1100 @ 3:00 pm
