Nanoscopium is a unique innovative beamline, which is dedicated to fast scanning multimodal and multi-lengthscale (30 nm à 1µm) X-ray imaging.
It offers simultaneous information in a quantitative manner and in the same experimental conditions, in 2D & 3D (tomography) about the elemental composition, chemical speciation and sample morphology.
The NANOSCOPIUM beamline is open for user proposals
The Nanoscopium hard X-ray (5-20 keV) nanoprobe beamline is dedicated to multi-technique X-ray imaging using fast scanning and high spatial resolution. The beamline develops and offers state-of-the-art X-ray nano-imaging and tomography techniques. Indeed, Nanoscopium offers a large portfolio of complementary imaging and spectroscopy methods, also in association to coherent diffraction imaging techniques. The cutting edge multitechnique possibilities available at the beamline pave the way towards quantitative imaging (morphology, elemental composition and chemical speciation) at hierarchical length-scales (30nm – 1µm).

Scanning multi-lengthscale imaging : the spatial resolution is adaptable in the 50 nanometre - 1 micron range
Complex samples with heterogene composition and tiny features of several millimetres samples can be easily studied by this unique zoom-in capability. The results shown below are published in "Highlights 2018 Synchrotron Soleil, page 8", https://www.synchrotron-soleil.fr/highlights/2018/.
