	Awareness of the need for FAIR data management has increased in recent years but examples of how to achieve this are often missing. Focusing on the large-scale instrument A4 at the MAMI accelerator, we transfer findings of the EMIL project at the BESSY synchrotron* to improve raw data, i.e. the primary output stored on long-term basis, according to the FAIR principles. Here, the instrument control software plays a key role as the central authority to start measurements and orchestrate connected (meta)data-taking processes. In regular discussions we incorporate the experiences of a wider community and engage to optimize instrument output through various measures from conversion to machine-readable formats over metadata enrichment to additional files creating scientific context. The improvements were already applied to currently built next generation instruments and could serve as a general guideline for publishing data sets. *G. Günther et al.

THMBCMO17	FAIR Data of Physical and Digital Beamlines	1231
	G. Günther, O. Mannix, O. Ruslan, S. Vadilonga HZB, Berlin, Germany
	Simulations play a crucial role in instrument design, as a digital precursor of a real-world object they contain a comprehensive description of the setup. Unfortunately, this digital representation is often neglected once the real instrument is fully commissioned. To preserve the symbiosis of simulated and real-world instrument beyond commissioning we connect the two worlds through the instrument control software. The instrument control simultaneously starts measurements and simulations, receives feedback from both, and directs (meta)data to a NeXus file - a standard format in photon and neutron science. The instrument section of the produced NeXus file is enriched with detailed simulation parameters where the current state of the instrument is reflected by including real motor positions such as incorporating the actual aperture of a slit system. As a result, the enriched instrument description increases the reusability of experimental data in sense of the FAIR principles. The data is ready to be exploited by machine-learning techniques, such as for predictive maintenance applications as it is possible to perform simulations of a measurement directly from the NeXus file. The realization at the Aquarius beamline * at Bessy II in connection with the Ray-UI simulation software and RayPyNG API * serves as a prototype for a more general application. * https://www.helmholtz-berlin.de/forschung/oe/wi/optik-strahlrohre/projekte/aquarius_en.html https://doi.org/10.1063/1.5084665 * https://pypi.org/project/raypyng

THMBCMO18	Advancements in Beamline Digital Twin at BESSYII	1236
	S. Vadilonga, G. Günther, S. Kazarski, R. Ovsyannikov, S.S. Sachse, W. Smith HZB, Berlin, Germany
	This presentation reports on the status of beamline digital twins at BESSY II. To provide a comprehensive beamline simulation experience we have leveraged BESSY II’s x-ray tracing program, RAY-UI[], widely used for beamline design and commissioning and best adapted to the requirements of our soft X-ray source BESSY II. We created a Python API, RayPyNG, capable to convert our library of beamline configuration files produced by RAY-UI into Python objects[]. This allows to embed beamline simulation into Bluesky[], our experimental controls software ecosystem. All optical elements are mapped directly into the Bluesky device abstraction (Ophyd). Thus beamline operators can run simulations and operate real systems by a common interface, allowing to directly compare theory predictions with real-time results[*]. We will discuss the relevance of this digital twin for process tuning in terms of enhanced beamline performance and streamlined operations. We will shortly discuss alternatives to RAY-UI like other software packages and ML/AI surrogate models.

THPDP101	Creating of HDF5 Files as Data Source for Analyses Using the Example of ALPS IIc and the DOOCS Control System	1570

	ALPS II is a light-shining through a wall (LSW) experiment to search for WISPs (very Weakly Interacting Slim Particles). Potential WISP candidates are axion-like particles or hidden sector photons. Axion-like particles may convert to light (and vice versa) in presence of a magnetic field. Similarly, hidden sector photons "mix" with light independent of any magnetic fields. This is exploited by ALPS II- Light from strong laser is shone into a magnetic field. Laser photons can be converted into a WISPs in front of a light-blocking barrier and reconverted into photons behind that barrier. The experiment exploits optical resonators for laser power build-up in a large-scale optical cavity to boost the available power for the WISP production as well as their reconversion probability to light. The Distributed Object-Oriented Control System - DOOCS - provides a versatile software framework for creating accelerator-based control system applications. These can range from monitoring simple temperature sensors up to high-level controls and feedbacks of beam parameters as required for complex accelerator operations. In order to enable data analysis by researchers who do not have access to the DOOCS internal control system to read measured values, the measurement and control data are extracted from the control system and saved in HDF5 file format. Through this process, the data is decoupled from the control system and can be analysed on the NAF computer system, among other things. NodeRed acts here as a graphical tool for creating HDF5 files.

To provide a comprehensive beamline simulation experience we have leveraged BESSY II’s x-ray tracing program, RAY-UI[*], widely used for beamline design and commissioning and best adapted to the requirements of our soft X-ray source BESSY II. We created a Python API, RayPyNG, capable to convert our library of beamline configuration files produced by RAY-UI into Python objects[**].
