Abstract
Diffraction limited synchrotron light sources (SR) and X-ray free-electron lasers share common interest and techniques. This lecture first address coherent X-ray imaging (CXI) of macromolecules and x-ray crystallography of protein molecules routinely studied with SR and XFEL. Then, we describe our recent work on extracting structural information inside the nanocrystal by use of Bragg coherent imaging [1] and its change upon the intense laser irradiation by use of time-resolved X-ray diffraction [2]. To extract a structural change of small gas phase molecules, on the other hand, commonly used techniques are Coulomb explosion imaging (CEI) and measurements of molecular frame photoelectron angular distributions (MFPAD) that is equivalent to photoelectron diffraction (PED). These techniques have been widely used with SR [3,4] and now becoming established methods to shoot molecular movies using pump-probe techniques using XFEL as a probe pulse [5-8].

Prof. Kiyoshi Ueda biography:
Kiyoshi Ueda graduated from Kyoto University in 1977 and completed a graduate course of Kyoto University in 1982 receiving his PhD. Since 1982, he has been working at Tohoku University, as a research associate (1982-1990), as an associate professor (1990-2003), and as a full professor (2003-2020). He is now a professor emeritus of Tohoku University and a distinguished adjunct professor of ShanghaiTech University since 2020. He was also a visiting scientist at University of Maryland in the United States (1985-87), an invited senior scientist at Daresbury Laboratory in the United Kingdom (1992-1993), an invited professor of Universite Paris Sud in France (1998), a guest professor of ETH Zurich (2022 and 2024) and a guest scientist of MBI Berlin (2023) and MPIK Heidelberg (2024).
He has been in the field of Atomic, Molecular, and Optical Physics, being the author or coauthor of 500+ papers (include 2 Nature, 6 Nature Photonics, 4 Nature Physics, 10 Nature Communications, 3 Science Advances, 2 PNAS, 9 PRX, 55 PRL, 5 JPCL), ~20 review articles and chapters of books. He has been giving more than 200 invited and plenary lectures in international conferences, workshops, symposiums, and seminars.
His research centers photoionization and photofragmentation of atoms, molecules, and clusters by synchrotron radiation, femtosecond lasers, and short-wavelength (EUV to X) free-electron lasers (FELs). Areas of special emphasis include ultrafast dynamic imaging, probing ultrafast electron and nuclear dynamics, characterizations of transient excited states and their decaying processes, and developing the new spectroscopic methods for these studies.
In the last decades, he has been organizing a series of international conferences and workshops on the relevant subjects such as photoionization, intense field phenomena, ultrafast phenomena, electronic spectroscopy, many particle spectroscopy, etc. and also serving as an international advisory board member and/or a program committee member for many international conferences that include VUVX (international conference on physics of vacuum-ultraviolet and X-ray physics), ICPEAC (international conference on photonic, electronic and atomic collisions), ICESS (international conference on electronic spectroscopy and structure), etc. He has been serving also as a program/proposal review panel for FEL facilities such as LCLS, FLASH, FERMI, and SPring-8, and as an advisory and/or review board for relevant facilities. He is also working as an editorial board for Physical Review X, J. Phys. B: At. Mol. Opt. Phys., Ultrafast Science, occasionally organizing a relevant special issue for various journals as a guest editor. He just completed the edits of the book “ultrafast electronic and structural dynamics” and submitted it to SpringerNature.
