Abstract Scope |
Multilayer Laue lenses (MLL) are diffraction-based X-ray optics that are especially suitable for the hard X-ray range. They exhibit a larger numerical aperture, NA, than compound refractive lenses and conventional Fresnel zone plates. In this work, we first present the implementation and characterization of an MLL at the DanMAX tomography beamline at MAX IV. Here the MLL is used for tomography via phase-contrast projection holography for materials science and bio-imaging. Coupled with a 150 Mpixel camera in the so-called Xtreme-CT setup, a large field-of-view (2 mm) is coupled with high spatial resolution (100 nm).
Next, we present the plans and status for implementing an MLL as an objective at the dedicated DFXM beamline ID03 at ESRF. Here the aim is to improve the spatial resolution to 30 nm. In addition, the larger NA will also improve data acquisition speed. |
