NanoExtreme: Nano-focus end-station with double-sided CO2 laser heating for experiments at ID27@ESRF

The ESRF has built a new high pressure beamline for nano-focused X-ray diffraction, fluorescence and imaging at the extremely brilliant source EBS. The upgraded beamline is in operation since end of 2021.

In the framework of the joint BMBF-funded project ‘NanoExtrem’, research groups from the Universities of Potsdam and Cologne have been contributing to the construction of this end-station by providing personnel and instrumentation:

15 – 60 keV in monochromatic mode, additional ‘pink’ beam mode beam focus of down to ~250 nm at 17.00 keV to achieve pressures >500 GPa XRD detection using EIGER2 X CdTe 9M detector sample goniometers for nano-focusing, YAG and CO2 laser heating or heavy duty experiments like Paris-Edinburgh cell or a 4 K cryostat in preparation: new experiments exploiting coherence of the beam and providing X-ray imaging capabilities.

This ‘high-flux nano-XRD’ beamline is optimized for the needs of the geo- and materials-science community for in-situ XRD and XRF studies at extreme conditions. It will be possible to study materials relevant to processes of the deep Earth or other planetary bodies in an unprecedented manner. We will present the overall design and provide first insights to performance parameters commissioned and used in first user experiments.

We acknowledge many divisions within the ESRF for construction and the German BMBF for financial support. BMBF project ‘NanoExtrem’ 05K2019: 05K19IP2 (Potsdam) and 05K19PK2 (Köln).
