32 32  The data acquisition system (DAQ) collects beamline and experimental data and writes them to hard disk. All data are stored along with a time stamp and, in case of train specific data, along with a (pulse) train ID. There are several ways to access beamline and experimental data stored in the DAQ during or after the beamtime be it programmatically via DAQ access libraries or after data conversion to HDF5 format. While the data transport to the user's home institution is possible, DESY hosts high power computing resources which can be used for analysis.
