Hartley, N.J.; Grenzer, J.; Lu, W.; Huang, L.G.; Inubushi, Y.; Kamimura, N.; Katagiri, K; Kodama, R.; Kon, A.; Lipp, V.; Makita, M.; Rode, Andrei


We present results from the SPring-8 Angstrom Compact free electron LAser (SACLA) X-ray free electron laser (XFEL) facility, using an X-ray pump, X-ray probe scheme to observe ultrafast changes in the structure of heated graphite. The 9.8 keV XFEL beam was focused to give an intensity on the order of  ∼ 1019 W/cm2, and the evolution of the diffraction pattern observed up to delays of 300 fs. The interplanar diffraction peaks weaken significantly within 10s of femtoseconds, but in-plane...[Show more]
