  • Tunable source of intense, narrowband, fully coherent, soft X-rays
    Patent number: 11770890
    Abstract: A device for generating soft x-rays includes an electron source configured to generate an electron beam comprising electron micro-bunches; an electron accelerator configured to accelerate the electron micro-bunches from the electron source; and a laser configured to generate a laser beam (536) colliding with the accelerated electron micro-bunches (534) in a counterpropagating direction to generate the soft x-rays by inverse Compton scattering. The electron source has a magneto-optical trap configured to produce an ultracold atomic gas; two counterpropagating excitation laser beams configured to produce a standing wave for inducing a periodic spatial modulation of the ultracold atomic gas along a beam propagation direction; and an ionization laser configured to induce photo-ionization of the ultracold atomic gas.
