Hard X-ray Micro/Nano-Probe Beamline P06

Description

The beamline houses two different experimental setups in separate hutches: the Microprobe (EH1) and the Nanoprobe (EH2). The Nanoprobe is mainly based on nanofocusing refractive x-ray lenses. Using refractive optics, nearly gaussian-limited nanobeams in the range from 50 to 100 nm can be generated in the hard x-ray energy range from 8 to 30 keV. In a high-coherence mode, the instrument is well suited for coherent diffraction imaging schemes, such as PtychographyScanning Transmission X-ray Microscopy plus a 2D detector used to gain phase information of the scattered/diffracted beam from suitable samples, which allows for increased resolution on small scanning areas.More info, reaching highest spatial resolution (below 10 nm) and sensitivity in the hard x-ray range. Tomographic scanning modes are routinely possible.

The Microprobe is a versatile experiment for scanning x-ray microscopy (STXMUsed for generating microscopic images of thin samples by raster-scanning them in an X-ray beam and measuring the flux of transmitted X-rays. The X-ray energy is scanned over an elemental absorption edge for chemical speciation.More info) with XRFUsed for studying the elemental composition of materials with spatial resolution.More info,XASUsed for obtaining information about chemical and structural properties of specific elements in materials such as liquids, gases, and solids.More info and XRD DiffractionUsed for atomic structure determination of materials, e.g. pharmaceuticals, catalysts, battery materials, and proteins.More info contrast. A KB system focusses a beam of some 10^10 photon/s down to 350 nm focus size in the energy range 5-21 keV. Compound refractive lenses are used at higher energies up to 50 keV. Advanced detector technology enables on-the-fly scanning schemes with millisecond dwell times per scan pixel. The ability to collect megapixel images in less than an hour facilitates series of 2D images for full 3D fluo-tomography, spectro-microscopy, time-resolved in-situ microscopy or other multi-dimensional microscopic experiments.
