Japanese Team Achieves Femtosecond Soft X-ray Hyperspectral Microscopy, Simultaneously Acquiring Spatial and Energy Information with Single Pulse
On August 21, the Japan Science and Technology Agency, RIKEN, and the University of Tokyo announced that a research team comprising Assistant Professor Yoko Takeo and Associate Professor Takashi Kimura from the Institute for Solid State Physics at the University of Tokyo, Assistant Professor Satoru Egawa from the Research Center for Advanced Science and Technology at the University of Tokyo, and Team Leader Makina Yabashi from the RIKEN SPring-8 Center, among others, successfully developed and implemented a femtosecond soft X-ray hyperspectral microscope. The findings were published on August 20 in the U.S. scientific journal *Optica*. This technology utilizes a single soft X-ray pulse from an X-ray free-electron laser (XFEL) to simultaneously acquire soft X-ray spectra transmitted through different positions of a sample, enabling...
