We have re-engineered the data acquisition system for the SPring-8 radiation monitors. Around the site, 81 radiation monitors are deployed. Seventeen of them are utilized for the radiation safety interlock system for the accelerators. The old data-acquisition system consisted of dedicated NIM-like modules linked with the radiation monitors, eleven embedded computers for data acquisition from the modules and three programmable logic controllers (PLCs) for integrated dose surveillance. The embedded computers periodically collected the radiation data from GPIB interfaces with the modules. The dose-surveillance PLCs read analog outputs in proportion to the radiation rate from the modules. The modules and the dose-surveillance PLCs were also interfaced with the radiation safety interlock system. These components in the old system were dedicated, black-boxed and complicated for the operations. In addition, GPIB interface was legacy and not reliable enough for the important system. We, therefore, decided to replace the old system with a new one based on PLCs and FL-net, which were widely used technologies. We newly deployed twelve PLCs as substitutes for all the old components. Another PLC with two graphic panels is installed near a central control room for centralized operations and watches for the all monitors. All the new PLCs and a VME computer for data acquisition are connected through FL-net. In this paper, we describe the new system and the methodology of the replacement within the short interval between the accelerator operations.

We integrated the utilities data acquisition into the SPring-8 accelerator control system based on MADOCA framework. The utilities data such as air temperature, power line voltage and temperature of machine cooling water are helpful to study the correlation between the beam stability and the environmental conditions. However the accelerator control system had no way to take many utilities data managed by the facility control system, because the accelerator control system and the facility control system was independent system without an interconnection. In 2010, we had a chance to replace the old facility control system. At that time, we constructed the gateways between the MADOCA-based accelerator control system and the new facility control system installing BACnet, that is a data communication protocol for Building Automation and Control Networks, as a fieldbus. The system requirements were as follows: to monitor utilities data with required sampling rate and resolution, to store all acquired data in the accelerator database, to keep an independence between the accelerator control system and the facility control system, to have a future expandability to control the facilities from the accelerator control system. During the work, we outsourced to build the gateways including data taking software of MADOCA to solve the problems of less manpower and short work period. In this paper we describe the system design and the approach of outsourcing.

The construction of the X-ray free electron laser facility (SACLA) in SPring-8 started in 2006. After 5 years of construction, the facility completed to accelerate electron beams in February 2011. The main component of the accelerator consists of 64 C-band RF units to accelerate beams up to 8GeV. The beam shape is compressed to a length of 30fs, and the beams are introduced into the 18 insertion devices to generate 0.1nm X-ray laser. The first SASE X-ray was observed after the beam commissioning. The beam tuning will continue to achieve X-ray laser saturation for frontier scientific experiments. The control system adopts the 3-tier standard model by using MADOCA framework developed in SPring-8. The upper control layer consists of Linux PCs for operator consoles, Sybase RDBMS for data logging and FC-based NAS for NFS. The lower consists of 100 Solaris-operated VME systems with newly developed boards for RF waveform processing, and the PLC is used for slow control. The Device-net is adopted for the frontend devices to reduce signal cables. The VME systems have a beam-synchronized data-taking link to meet 60Hz beam operation for the beam tuning diagnostics. The accelerator control has gateways to the facility utility system not only to monitor devices but also to control the tuning points of the cooling water. The data acquisition system for the experiments is challenging. The data rate coming from 2D multiport CCD is 3.4Gbps that produces 30TB image data in a day. A sampled data will be transferred to the 10PFlops supercomputer via 10Gbps Ethernet for data evaluation.
