NXarpes, the Data File Standard for ARPES in NeXus — •Moritz Hoesch¹, Pavel Dudin², and Tobias Richter³ — ¹DESY Photon Science, Hamburg, Germany — ²Synchrotron Soleil, Gif-sur-Yvette, France — ³European Spallation Source, Lund, Sweden

NeXus is a common data format for neutron, x-ray, and muon science. It is being developed as an international standard by scientists and programmers representing major scientific facilities in order to facilitate greater cooperation in the analysis and visualization of neutron, x-ray, and muon data (cited from [1]). Diamond Light Source has adopted the NeXus standard, including for the instruments HR-ARPES and nano-ARPES on beamline I05 [2]. The specific NXarpes format, deliberately focusing on the essentials and thus expandable without deviation from the standard is available to the community [3]. In this presentation I will show examples of NXarpes data files and discuss the reception of this format by the community of ARPES users.
