内容記述
The ITER Remote Experimentation Centre (REC) project (one of the three sub-projects of the InternationalFusion Energy Research Centre (IFERC)) is progressing under the agreement between the Government of Japanand the European Atomic Energy Community for the joint implementation of the Broader Approach (BA) activitiesin the field of fusion energy research. The objectives of the REC activity are to identify the functions andsolve the technical issues for the construction of the REC for ITER at Rokkasho, and to develop the remoteexperiment system and verify the functions required for remote experimentation by using the Satellite Tokamak(JT-60SA) facilities to facilitate the future exploitation of ITER and JT-60SA. The functions of REC will be tested,and the total system will be demonstrated using JT-60SA and existing facilities in the EU, such as JET and WEST.The hardware of the REC has been prepared in Rokkasho Japan, which has the remote experiment room witha large video wall to show the plasma and operation status, IT equipment and a storage system by the reuse ofthe Helios supercomputer tape library. A broadband network infrastructure of 10Gbps has been installed connectedto SINET5. Using this network system, fast data transfer from ITER to REC was examined in 2016, and thetransfer of the data volumes expected for the initial ITER experiments has been demonstrated. A secure remoteexperimentation system has been developed, using JT-60SA, that has functions for preparing and setting of shotparameters, viewing the status of control data, streaming of the plasma status, data-exchange function of shotevents, and monitoring of the facility operation. Remote data analysis techniques, data visualisation software, adocumentation management and experiment planning system and numerical simulation codes for the preparationand performance estimation of discharges have also been developed.
