WCO205 | Upgrade of SACLA DAQ System Adapts to Multi-Beamline Operation | 22 |

||
We report the data acquisition system (DAQ) for user experiments at SACLA (the SPring-8 Angstrom Compact Free Electron Laser). The system provides standardized experimental framework to various XFEL users since March 2012. It is required to store shot-by-shot information synchronized with the XFEL beam of 60Hz at the maximum repetition rate. The data throughput goes up to 6 Gbps with TOF waveforms and/or images (e.g. X-ray diffraction images) from experiments. The data are stored to the hierarchical storage system capable of more than 6 PByte at the last stage. The DAQ system incorporates with prompt data processing performed by a 14 TFlops PC cluster as well as on-line monitoring. In 2014, SACLA will introduce the third beamline to increase the capacity of experiments. On the DAQ side, it is a challenge to operate multiple experiments simultaneously. The control and data stream will be duplicated and separated for beamlines. A new central server to manage each beamline condition in one place will help increase the efficiency of setup procedure and reduce risks of mishandling between beamlines. | ||
