A second NanoMAX experimental station, relying on Fresnel Zone Plate (FZP) focusing, is currently being realised. In its mature state, it will provide an X-ray beam focused down to a 30 nm spot, with a long term goal of 10 nm. The imaging endstation will rely on position monitoring at the nanometer scale using optical interferometry and will provide a single rotation axis for tomographic measurements.
The FZP station will feature a large pixel detector in the forward direction for diffraction and coherent imaging methods. Two Silicon Drift Diode X-ray fluorescence detectors will be used for elemental mapping. The station will operate in vacuum and have liquid nitrogen sample cooling. First test experiments in air were conducted December 2021. The the goal is to have the complete microscope, with detector flight tube installed and partly commissioned at the end of the 2022.
Proposal call information
The proposal call, with deadline March 14th 2022, is open for applications to this station. All planned functionality will, however, not be available during the beamtime period, ending February 2023. The goal is to be able to perform scanning 2D and tomography measurements under vacuum, at room temperature, with XRF detectors, and the Eiger2 area detector.
