Times Cited Count：2 Percentile：18.73(Nuclear Science & Technology)In JT-60U the data processing system, providing the data acquisition, producing the diagnostic data base, and communicating with the JT-60U control system. The MSP-ISP was replaced by a new Inter-Shot Processor based on the UNIX-OS of a workstation (UNIX-ISP) in 2005. The performance of UNIX-ISP is 2 times as high as that of the MSP-ISP in a stand-alone test using the data conversion program of the CXRS data. Thus we can expect the reduction of the processing time by the optimization of the total sequence. For the remote experiment, we have developed a system called RMSVR with which we can set discharge parameters from the remote site, and thereby the consistency of input parameters is checked. The high security of the remote experiment system is established by the certification and the encrypted communication based on ITBL. A verification test between a university and JAEA Naka indicates that the system using the HTTPS protocol is suitable for the remote experiment.

We are constructing a hierarchical remote research system, which consists of remote experiment, remote analysis, and remote diagnostic. In a remote collaboration, it is important to maintain the security of the system, as well as to share the information, atmosphere and presence between the participants. For the latter purpose, we developed a video conferencing system, and a video streaming system that can deliver the images of the JT-60 control room. Furthermore, a development of the remote analysis system called "VizAnalysis" has been started. And to assist the remote analysis, we developed a web based software system called "VizSquare". In the JT-60 tokamak at JAERI, security and authentication methods on a computer network and a new communication tool are developed, and probably they will be applied to the remote participation of ITER.

Times Cited Count：7 Percentile：45.11(Nuclear Science & Technology)Data processing system in JT-60 has been used CAMAC widely for control and data acquisition of plasma diagnostic. However, it has passed over fifteen years from the operation, and the problem is caused for maintenance and function enhancement by the deterioration. Then, Mini-computer and microcomputer ,which control the CAMAC system were replaced workstation based on UNIX-OS, and these system were remodeled by developing the application software for screen control by GUI and for constructing environment of remote diagnostic through the network. In addition, CAMAC device driver for Linux has been developed in for next CAMAC control system.
