Picosecond, Tunable, High Peak Brightness Hard X-Ray Inverse Compton Source at Duke Storage Ring

We suggest a state-of-the-art X-ray source using a compact electron storage ring with modest energy (less then 1 GeV) and a high power mm-wave as an undulator. A source of this type has X-ray energies and brightness comparable with third generation synchrotron light sources while it can be very compact and fit in a small university or industrial laboratory or hospital. We propose to operate an isochronous mm-wave FEL and a hard X-ray Inverse Compton source at the Duke storage ring to test this concept. Resonant FEL conditions for the mm-wave will be provided by the off-axis interaction with an electromagnetic wave. A special optical resonator with holes for the c-beam is proposed for pumping a hard X-ray Inverse Compton source with very high brightness. Simulation results of mm-wave FEL operation on the Duke storage ring are discussed. Expected performance of mm-wave FEL and bard X-ray Inverse Compton source are presented.
