| Research Abstract |
We published a review paper describing the basic concept of pulsed coherent x-ray solution scattering (PCXSS) that we are proposing. We developed environmental cells to be used for sample holders which enable measurement in a controlled environment. By numerical simulation, we designed experimental configurations and developed algorithms for data analysis. We performed PCXSS measurement by using an x-ray free-electron laser facility SACLA, and succeeded in recording single-shot coherent x-ray diffraction patterns.
