Description
Since 2019 HERMES beamline [1] implemented and is continuously optimizing a dedicated setup to perform ptychography experiments and such push the spatial resolution limit beyond the present Fresnel zone plates limitations, i.e. 30 nm. Here we present the mechanical, optical, hardware and software integration of the setup in the STXM instrument, along with the functional workflow from a user perspective. This includes the entire process from setting up the working geometry parameters to the reconstruction process using PyNX [2]. Few examples will be equally presented demonstrating the actual capabilities of the setup.
