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).

The 25th User Proposal Call (AP25) of Synchrotron Soleil is open with 16th September 2019  14:00 h (French time) proposal deadline, please find more information at https://www.synchrotron-soleil.fr/en/users.

Scanning multi-lengthscale imaging: the spatial resolution is readily 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/.
