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).
Multi-lengthscale elemental distribution mapping is available at the beamline
The results shown below are published in "Proceedings of SPIE, X-Ray Nanoimaging: Instruments and Methods III" under paper N° 10389-41
