Previous work has shown that it is possible to use consecutive X-ray pulses to collect diffraction patterns from individual crystals. Here, we exploit the MHz pulse structure of the European XFEL to obtain two complete datasets from the same lysozyme crystal, first hit and the second hit, before it exits the beam. The two datasets, separated by <1 micros, yield up to 2.1 A resolution structures. Comparisons between the two structures reveal no indications of radiation damage or significant changes within the active site, consistent with the calculated dose estimates. This demonstrates MHz SFX can be used as a tool for tracking sub-microsecond structural changes in individual single crystals, a technique we refer to as multi-hit SFX. Megahertz pulse trains enable multi-hit serial femtosecond crystallography experiments at X-ray free electron lasers.,Holmes S, Kirkwood HJ, Bean R, Giewekemeyer K, Martin AV, Hadian-Jazi M, Wiedorn MO, Oberthur D, Marman H, Adriano L, Al-Qudami N, Bajt S, Barak I, Bari S, Bielecki J, Brockhauser S, Coleman MA, Cruz-Mazo F, Danilevski C, Dorner K, Ganan-Calvo AM, Graceffa R, Fanghor H, Heymann M, Frank M, Kaukher A, Kim Y, Kobe B, Knoska J, Laurus T, Letrun R, Maia L, Messerschmidt M, Metz M, Michelat T, Mills G, Molodtsov S, Monteiro DCF, Morgan AJ, Munnich A, Pena Murillo GE, Previtali G, Round A, Sato T, Schubert R, Schulz J, Shelby M, Seuring C, Sellberg JA, Sikorski M, Silenzi A, Stern S, Sztuk-Dambietz J, Szuba J, Trebbin M, Vagovic P, Ve T, Weinhausen B, Wrona K, Xavier PL, Xu C, Yefanov O, Nugent KA, Chapman HN, Mancuso AP, Barty A, Abbey B, Darmanin C Nat Commun. 2022 Aug 11;13(1):4708. doi: 10.1038/s41467-022-32434-6.
