Experimental setup. a The scattering geometry in which coherent X-rays illuminate the masked LBCO 1/8 sample and the CDW Bragg peak is measured on a CCD detector. b A SEM image of the LBCO 1/8 single crystal with a Au mask fixed on top. Numbers 1–16 indicate the 16 pinholes drilled in the Au mask using a focused ion beam (FIB) prior to being fixed on the crystal. The white scale bar represents 50 μm. c A zoomed SEM image of pinhole #10, through which most of our data were taken. The white scale bar represents 5 μm
