We present two significant projects, namely OASYS (OrAnge SYnchrotron Suite) and DABAM (DAta BAse for mirror Metrology), which emerged as notable outcomes from MEADOW2013. Both projects have had a considerable impact on the field of X-ray science and have provided valuable resources for researchers and scientists. OASYS [1], an open-source software suite developed for the simulation and analysis of X-ray beamlines, has been instrumental in enhancing the design and optimization of beamlines in upgraded storage rings. Through its comprehensive toolset (add-ons), OASYS facilitates ray tracing, wavefront propagation, source modeling, and data analysis, thereby enabling researchers to study X-ray optics and simulate beamline performance. OASYS continues to evolve, incorporating new features and functionalities to meet the challenges of the X-ray science community. DABAM [2] is a collaborative project aimed at creating a comprehensive database for mirror profiles measured in the metrology laboratories of synchrotron facilities and research institutions worldwide. DABAM serves as a centralized repository of information on the error profile characteristics of mirrors used in X-ray beamlines. DABAM facilitates the simulation of real mirrors in ray tracing and wavefront propagation simulations and is completely integrated into the OASYS environment. This talk discusses the status and ongoing developments of both projects. It highlights the impact of OASYS and DABAM in adapting and upgrading many beamlines to the new low-emittance storage rings in operation (EBS-ESRF), being implemented (APS-U), or in project (ALS-U, etc).

12:30 PM - 1:00 PM
When dealing with experiments conducted at 4th-generation synchrotron radiation and free electron laser beamlines, the primary challenge for X-ray optical elements lies in achieving and maintaining focused X-ray beams of high intensity, possessing near-perfect wavefront quality and exceptional stability. Optical elements necessitate more stringent specifications compared to other applications due to the shorter wavelength and ultra-small emittance of the radiation generated by these sources. In the case of diffraction-limited light sources producing coherent photons, it is crucial to preserve well-controlled wavefronts. The degradation of the wavefront proves detrimental to phase-sensitive imaging techniques such as Tomography. For coherent X-ray scattering experiments employing techniques like X-ray Photon Correlation Spectroscopy, Coherent Surface Scattering Imaging, and Coherent X-ray Diffraction Imaging, wavefront uniformity holds particular significance. X-ray optics must be manufactured with a near-perfect shape, and automatically and consistently align and focus the beam according to experimental requirements. Furthermore, they should be capable of providing real-time correction in response to wavefront deformations. At the APS, we have successfully demonstrated the practical application of two methods: i) utilizing a Neural Network (NN) model to autonomously control deformable mirrors with remarkable precision and control. The NN is trained to establish a time-dependent relationship between the hardware setup and the wavefront properties during experiments. ii) Employing Bayesian optimization with Gaussian processes to automatically align and stabilize the focusing optical systems of hard X-ray synchrotron radiation beamlines. This approach utilizes ultra-realistic digital twins constructed using the OASYS simulation framework and enables effective steering of the optical assembly.
