The collaboratory for the EAST is available, which possesses the capacity to further advance active research on EAST. In doing so, the distance between local researchers and participators over the world is just a click away. To feature the system with the function of remote control, the functional business logic is all encapsulated in the mandatory controls, which can potentially boost the computing capability of the clients with a B/S framework. At the same time, the EAST collaboratory embraces powerful on-line data exchange and data management functions via state-of-the-art XML Web services. With the goal of accessing and analysing the pivotal experimental data on-line, a data analysis system is implemented in JAVA. Finally as a valuable asset of the EAST collaboratory the function of videoconference will be also covered in this contribution.展开更多

MDSplus, a special software package for fusion research, has been used successfully as a central repository for analysed data and PCS （Plasma Control System） data since the debugging experiment in the spring of 2006 [1]. In this paper, the reasons for choosing MDSplus as the analysis database and the way to use it are presented in detail, along with the solution to the problem that part of the MDSplus library does not work in the multithread mode. The experiment showed that the data system based on MDSplus operated stably and it could provide a better performance especially for remote users.展开更多
