Example of the setup at MEC of a typical experiment and close-up of typical samples (inset). The target sample is in the center of the MEC vacuum chamber, on a motorized alignment stage with six degrees of freedom. The optical beam (in green) is overlapped on the sample with the LCLS X-ray beam using a motorized lens for steering. Long-distance microscopes are used to image both beams on a Ce:YAG scintillating target. An HAPG X-ray Thomson spectrometer records X-ray back-scatter. A large-area diffracton detector (CSPAD-560k) records elastic scatter for a solid angle of approximately 0.75 sr. |
