![]() With minute surface and alignment errors affecting the wavefront downstream, new beamlines must be treated as interdependent optical systems, where adaptive corrections coupled to high accuracy feedback are ultimately required to achieve and maintain the wavefront properties in routine operations. With a focus on delivering high coherent flux to demanding experimental applications in scattering, dynamics, and nanoscale probes, the tolerances on optical components have never been more stringent. Department of Energy (DOE) National Laboratories are driving an intense effort to develop beamline optical systems that are matched to the new source properties of free electron lasers (FEL) and diffraction limited storage rings (DLSR).
