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.

| 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. | ||
