The Trend of fusion energy research and development in the participant party and countries in the ITER project

Yoshida, Hidetoshi

Genshiryoku eye, 53(7), p.31 - 33, 2007/07

The basic policy and its background for fusion energy research and development is surveyed in the Participant Party and Countries in the ITER Project. The activity trend of the European Domestic Agency and EFDA, including Broader Approach activity, is described. The new trend for fusion energy research and development in the United States of America is presented. The current status of the Republic of Korea, the People's Republic of China and the India and so on is also surveyed.

Current status and future prospects of the JT-60U control system

Yonekawa, Izuru; Kawamata, Yoichi; Totsuka, Toshiyuki; Akasaka, Hiromi; Sueoka, Michiharu; Yoshida, Hidetoshi

Fusion Engineering and Design, 71(1-4), p.11 - 15, 2004/06

 Times Cited Count:5 Percentile:35.25(Nuclear Science & Technology)

The JT-60 control system based on workstation and VME-bus system features with UNIX system has been successfully performed at JT-60U advanced plasma experiment. The various hardware modifications and the adoption of the advanced plasma control algorithms have been continued to the JT-60 control system since its upgrade in 1991. The ZENKEI, supervisory control system, has entirely remodeled from its original 16 bits minicomputer and CAMAC system to the combination of workstation and VME-bus system configuration with Ethernet communication network system. The plasma control system executes real-time plasma equilibrium control command calculation within 250msec control cycle time. Each plant control subsystems are also modified along with same design concept to the ZENKEI. Currently, the minor modifications of the control system have been considered to realize longer pulse of discharge experiments without major change of the JT-60 equipment. Nearly 60 seconds of pulse length up to Ip=2MA, Bt=2T, PNBI=10MW($$sim$$30sec) plasma experiments will start from October in 2003.
