Electronic Laboratory Notebooks (ELN) are a building block of the recently establishing FAIR data management procedures in research and the publication process of research data, by documenting the experimental details, data collection and analysis process. They enable the capture and management of experimental results in a collaborative approach. Furthermore, they provide an interlinking with the utilized techniques and holding information’s on the investigated specimens. Thus, ELNs are the entrance point to an experiment for any scientist keen to understand and reproduce an experiment. The Data from Photon and Neutron Experiments (DAPHNE4NFDI) data life cycle is depicted in Figure 1, ELNs are part of the documentation step during the data collection. DAPHNE4NFDI is one of the 26 consortia within the German National Research Data Infrastructure (Nationale Forschungsdaten Infrastuk­tur, NFDI). The aims of this initiative are the development and improvement of data management tools for research data from large scale Photon and Neutron (PaN) research infrastructures; similar activities are undertaken at other PaN facilities at EU level and worldwide. Research at PaN facilities is always a joint undertaking of the facilities operating the instruments and the external user groups which poses additional challenges for collaborative research data management and comprehensive experiment documentation.
