Femtosecond nanocrystallography

Nanocrystals flow in their buffer solution in a gas-focused, 4-μm-diameter jet at a velocity of 10 m s−1 perpendicular to the pulsed X-ray FEL beam that is focused on the jet. Inset, environmental scanning electron micrograph of the nozzle, flowing jet and focusing gas30. Two pairs of high-frame-rate pnCCD detectors12 record low-and high-angle diffraction from single X-ray FEL pulses, at the FEL repetition rate of 30 Hz. Crystals arrive at random times and orientations in the beam, and the probability of hitting one is proportional to the crystal concentration.
