Figure 1. Schematic diagram of an LCP-SFX experiment at LCLS.
LCP jet delivers crystals in a continuous stream of LCP to the interaction point with an incident XFEL beam focused to a 1.5 µm diameter spot by Kirkpatrick-Baez (K-B). Single shot diffraction patterns from microcrystals at different orientations are recorded by a Cornell-SLAC Pixel Array Detector (CSPAD) at 120 Hz. LCP jet, the detector and the entire XFEL beam path are under vacuum.
