The X-Ray Optics and Applications group of LMN works on various fields of research which involve the control of x-rays with ultimate precision. We develop instrumentation for experiments at synchrotrons, x-ray free electron lasers, and x-ray tubes. This includes diffractive x-ray lenses (Fresnel zone plates) as well as refractive lenses for imaging and probing of matter on a micro- and nanometer scale. Our optics hold the resolution world record in x-ray microscopy.
In addition to focusing optics we fabricate diffractive gratings for the exposure of periodic nanostructures using extreme UV interference lithography. This unique method provides the smallest structures ever obtained by photon based lithography.
Interferometric imaging techniques using hard x-rays and cold neutron radiation also rely on specialized micro-fabricated gratings. The possibility to use this technique not only with synchrotron radiation but also with incoherent x-rays from tube sources makes the technique interesting for commercial applications.
Similar structures are applied in x-ray scattering investigations on nanofluidic systems to investigate the short-range structure liquid in confined geometries.
