Surface roughness and the scattering of glancing‐angle x rays: Application to x‐ray lenses

Hollow glass fibers can guide x rays because glancing‐angle collisions with a smooth glass surface are highly reflective. Surface roughness decreases this reflectivity. We have developed relatively simple expressions for the effects of surface roughness on x‐ray scattering, and we relate our results to the theoretical efficiency of x‐ray lenses formed from bundles of hollow glass fibers.
