Abstract: An apparatus and methods for small-angle electron beam scattering measurements in a reflection or a backscattering mode are provided. The apparatus includes an electron source, electron collimation optics before a sample, electron projection optics after the sample, a sample stage capable of holding the sample, and a electron detector module. The electrons emitted from the source are collimated and positioned to impinge nanostructures on the sample. The signals resulting from the interactions between the impinging electrons and the nanostructures are further magnified by the electron projection optics to reach a sufficient angular resolution before recorded by the electron detector module.

Abstract: The disclosure provides an apparatus for aligning first and second plates that are parallel to each other and have the same orientation. The apparatus includes a detector that detects composite small-angle X-ray scattering emitted from patterns of the first and second plates that are perpendicularly impinged by X-ray, and a moving unit that aligns the first and second plates according to a composite amplitude distribution of the composite small-angle X-ray scattering. Therefore, the first and second plates are aligned to each other accurately.
