  • Abstract

  • In my talk I will start from the basics of coherent x-ray diffractive measurements (CXDI) and will present recent results of the catalytic reaction studied by CXDI at ID01 beamline at ESRF. Next, I will show results of the Single Particle Imaging (SPI) reconstruction of the 70 nm virus obtained in the frame of the SPI consortium collaboration at LCLS [1].
    Then, I will present results of Hanbury Brown and Twiss interferometry performed at different X-ray Free-Electron Lasers (XFELs) [2-4] and will finish my presentation by the results of Ghost Imaging experiment performed at FLASH FEL at DESY.
