Very Long-Distance MLL Development and in-situ & in-operando Setups for X-ray Nanodiffraction Analysis of Thin Films and Energy Components

The project focuses on the development of multilayer Laue lenses (MLLs) for ID13. Previous experiments have already shown focal spot sizes down to ~23 nm with diffraction efficiencies up to about 29 %. The main instrumental goal of this LTP is the development of two types of MLL optics, namely (i) “very long-distance” with a focal length of up to ~150 mm, a working distance of >100 mm (@ 12 keV) and an optics aperture of up to ~ 200 µm × 200 µm and (ii) “a new high resolution” lens pair with a focal spot size down to half of the present value, reaching ~10 nm. The MLLs will be used to perform (i) in-situ micromechanical tests on thin films and fibers using a dedicated indenter and (ii) in-operando electro-chemo-mechanical tests on solid state batteries (SSBs). For this purpose, the indenter from MI-1355 will be further developed by implementing new sample mounts, wedge and flat-punch tips and tensile option. Additionally, an adaptable in-operando cell to test SSBs will be designed.
