BackgroundHefei Light Source (HLS-II) is a dedicated synchrotron radiation source with featured the characteristics spectrum in vacuum ultraviolet and soft X-rays regions. The user's experiment efficiency and data processing efficiency are the principal indicators of HLS-II operation.PurposeThis study aims to develop an experimental data management system based on SciCat to improve the user's experimental and data processing efficiency.MethodsAs the core component of HLS-II experimental data management system, the metadata system was designed and developed within the framework of SciCat, an open source metadata catalog framework used to realize the unified management of the whole life cycle of experimental data of large scientific devices. Data acquisition service, metadata system, file storage system and data analysis platform were integrated into SciCat, and the hierarchical data format 5 (HDF5) was adopted as the standard experimental data format. Interface between existing user service systems and SciCat was implemented to achieve the management of the whole experiment and experimental data lifecycle, including user authentication, proposal application, expert approval, machine time schedule, data acquisition, data storage, data analysis and data publication.Results & ConclusionsThe system has been deployed and functionally tested at the soft X-ray microscopy experimental station of HLS-II, satisfying all design requirements. |
