Abstract Scope |
The TXM at beamline 32-ID of the APS at Argonne National Laboratory has been tailored for high throughput and high spatial resolution in operando nanotomography experiments. Thanks to a constant R&D effort, it emerged as a highly productive instrument, especially in the domain of Materials Science.
Here, we will report recent upgrades that led the instrument to unprecedented level of performance. New optics conjugated with the enhancement of key mechanical components enabled 1 mn long tomographic acquisitions, to improve Zernike phase contrast measurement for materials like graphite and to achieve 3D spatial resolution of 13 nm, which is a record for a TXM and comparable to the resolution of the best hard X-ray ptychography microscopes. Then, we will present 3D characterization of material and systems in operando, like Portland cement formation over 10h with 1 min temporal resolution, Al-Cu alloy experiencing deformation or PGM-free electrocatalysts undergoing pyrolysis. |
