In the framework of the BMBF-funded ‘NanoExtrem' and ‘NanoExtrem-2' projects, the high-pressure beamline ID27 at the European Synchrotron Radiation Facility (ESRF) has undergone a significant upgrade, with the result of the construction of an end station for nano-focused X-ray diffraction (XRD), fluorescence (XRF), imaging (XRI) and emission spectroscopy (XES).
The latest upgrade to the end-station includes as a Von-Hámos X-ray emission spectrometer, enabling simultaneous XRD and XES measurements at high pressures. This enhancement will facilitate in-depth studies of structural and electronic properties under extreme conditions.
To test the setup, high-pressure diamond anvil cell (DAC) experiments were conducted at ambient temperature up to pressures of 50 GPa, focusing on the pressure induced spin transition of natural magnesiosiderite.
These experiments demonstrated the capability of the combined XRD and XES approach to capture structural and electronic transitions with high precision and efficiency. The results highlight the potential of the ID27 beamline for advanced studies of materials under high-pressure conditions, paving the way for novel insights into the behavior of complex systems.
