Bill Graves and colleagues are pursuing development of a very compact XFEL based on inverse Compton scattering from a nanopatterned electron beam. CXFEL depends on a novel method to produce transform-limited X-ray output in all dimensions, that is with all photons in a single degenerate quantum state. This method avoids the noise amplification of SASE by imprinting a well-defined coherent modulation on the electrons via diffraction in a thin crystal grating. The method allows for coherent control of the phase, frequency, bandwidth, pulse length and amplitude of the X-ray pulses and enables a variety of two-color or multicolor experiments with precisely tunable femtosecond delays for pump-probe experiments and perhaps even subcycle phase-locking of the multiple colors. This source is ideal for emerging techniques such as coherent diffractive imaging, stimulated X-ray Raman spectroscopy and Fourier transform resonant inelastic X-ray scattering for studying molecular dynamics and correlated electron effects.
