Description
The European Spallation Source (ESS) will operate a suite of diffractometers. One of the first operational instruments will be DREAM [1], a diffractometer developed and built for ESS by the consortium Forschungszentrum Jülich (Germany) and Laboratoire Léon Brillouin (France).
To ensure smooth operation even for the first-time users, the ESS Data Management and Software Centre is developing an integrated data pipeline linking all the steps from data acquisition and live visualisation to data analysis. To test this pipeline during the construction phase of ESS and of its instruments, we use instrument simulations with McStas [2] combined with GEANT4 [3] due to the complex three-dimensional geometry of new 10B detectors of the ESS diffractometers. Here we report on preliminary implementations of the data processing pipeline for diffraction data from raw NeXus [4] event files to data archiving.
