FWKT data management is a family of software tools for connecting instruments and scientific records in laser-plasma experiments at HZDR. At DRACO, the laser trigger, diagnostic files from instrument PCs, and operator descriptions of the target, laser and vacuum conditions together describe an experimental shot. The software brings these sources into a shared campaign record while allowing instruments to keep their existing acquisition software and file formats.
The TANGO shotcounter detects laser triggers, and the shot authority assigns their shared shot number. LabFrog captures campaign and shot context. The DAQ File Watchdog monitors instrument output, attributes files to shots and sends source events through Kafka. DAMNIT-web-hzdr combines these events with LabFrog's SQLite exports, builds canonical NeXus/HDF5 campaign files and provides a web interface for inspection. The SciCat plugin registers the campaign outputs for discovery. Bulk detector data remains on shared storage, linked to its scientific context.
Two complementary tools support the interpretation of instrument data. The Laser Shot Aligner reconstructs shots from existing files with human review and builds per-shot NeXus containers. NeXus Design Studio provides the instrument catalogue, helps map metadata and instrument formats to NeXus, and validates the resulting files. Together, these tools connect acquisition, beamtime documentation, data review and reuse. The system is still a pilot.
