We describe an experiment designed to probe the electronic damage induced in nanocrystals of Buckminsterfullerene (C₆₀) by intense, femtosecond pulses of X-rays. The experiment found that, surprisingly, rather than being stochastic, the X-ray induced electron dynamics in C₆₀are highly correlated, extending over hundreds of unit cells within the crystals¹.

This protocol presents the operation and principles of micron-scale cylindrical and planar cryogenic liquid jets. Until now, this system has been used as a high repetition rate target in laser-plasma experiments. Anticipated cross-disciplinary applications range from laboratory astrophysics to material science, and eventually next-generation particle accelerators.
