In a new paper published last week[ref]Daurer2021[[/tooltip]]Daurer, B. J.; Sala, S.; Hantke, M. F.; Reddy, H. K. N.; Bielecki, J.; Shen, Z.; Nettelblad, C.; Svenda, M.; Ekeberg, T.; Carini, G. A.; Hart, P.; Osipov, T.; Aquila, A.; Loh, N. D.; Maia, F. R. N. C. & Thibault, P., Ptychographic wavefront characterization for single-particle imaging at x-ray lasers, Optica (2021)[/ref], we show how ptychography can be used to characterize the extremely short and powerful X-ray pulses generated at the Linac Coherent Light Source (LCLS, SLAC Stanford, USA), one of the few X-ray free-electron lasers operating in the world. The work is the result of a broad collaboration, including present and former members of the Maia group (Uppsala University, Sweden) and the Loh group (National University of Singapore).
This paper follows a previous work[ref]Sala2020[[/tooltip]]Sala, S and Daurer, B J and Odstrcil, M and Capotondi, F and Pedersoli, E and Hantke, M F and Manfredda, M and Loh, N D and Thibault, P and Maia, F R N C, Pulse-to-pulse wavefront sensing at free-electron lasers using ptychography, J. Appl. Crystallogr. (2020)[/ref] that was conducted with many of the same collaborators to characterize the X-ray pulses generated at FERMI, Italy’s very own free-electron lasers, also hosted here in Trieste.
