Data acquisition system to handle multiple experiments at the data rate of 12 Gbps at X-ray free-electron laser facility SACLA

In 2014, the control and data acquisition (DAQ) system for user experiments was reorganized at the X-ray free electron laser facility, SACLA. The upgraded DAQ system now supports concurrent experiments on two beamlines. In order to secure data throughput and introduce access restriction, the data stream and control communications are physically separated for each beamline. The system can handle two data streams of as much as 12 Gbps from two concurrent experiments. Because the system is scalable, it is adaptable to the future upgrades of as many as five beamlines.
