Autonomous SAXS mapping of sDSA sample. Experimental transmission small-angle x-ray scattering (TSAXS) data collected as a function of position for a selective directed self-assembly (sDSA) combinatorial sample. Sample was a grid of lithographically-defined chemical patterns (varying pitch and dose) with a blend of block copolymer materials cast on top. Measurement positions were selected machine-learning algorithm implementing a Gaussian Process (GP) method. Dataset contains raw SAXS detector images, as well as analysis results converting the image into linecuts in various azimuthal directions, and fitting those linecuts to extract peak position, width, and intensity.
