Russian Experience in Development and Testing of the Elements of Remote Participation in ITER Experiment

The ITER thermonuclear reactor is being built in France near the Cadarache nuclear center jointly by the countries participating in the project—Russia, the European Union, China, India, Korea, Japan, and the United States. The project plans the remote scientific participation in the pilot program and access to data from home agencies. The Russian Center for Remote Participation is being created in Troitsk at the Russian Domestic Agency ITER (Institution Project Center ITER) and currently the most advanced in terms of available functionality; on its basis, the joint work is carried out with the International Organization ITER (IO ITER) for developing technologies and principles of remote participation in the experiment for other participants. The article presents the results of investigations on protocols, methods, and channels for data transmission through existing networks and related information security issues including the network zoning. The elements of access to the ITER real-time data acquisition system through the EPICS facility control system gateway are described, various tools for remote participation planned for use within the ITER project, such as screen sharing and real-time data viewing, are tested. On the basis of the results of the work of the IO ITER, the requirements are formulated for remote connection of partners to the ITER resources.
