To introduce and experimentally demonstrate convergent-beam X-ray crystallography with attosecond hard-X-ray pulses for resolving molecular electron dynamics at sub-angstrom and sub-femtosecond scales.
Coupled high-power attosecond pulses from a hard-X-ray free-electron laser with high-numerical-aperture dispersive optics, specifically multilayer Laue lenses.
Used the convergent-beam geometry to encode pulse arrival times and positions across the crystal surface into snapshot diffraction patterns.
Demonstrated that diffraction patterns form Bragg streaks encoding time with deep sub-femtosecond sampling precision over spans of tens of femtoseconds.
Increased the yield of observable, fully integrated reflections per snapshot pattern, improving the throughput and precision of serial crystallography for small molecules.
