Abbreviation of the Tokamak type nuclear fusion test device jointly developed by the EC. It was developed and constructed at the Cullum Laboratory (Abingdon, suburb of Oxford) in the UK with joint funding from the EC. It started plasma nuclear fusion experiment operation in 1983. It is called one of the four largest tokamaks in the world along with Japan's JT-60, America's TFTR, and Russia's T-15, and has achieved results by aiming for break-even conditions. Development was carried out by Euratom, a joint operation of EC member states, and researchers were gathered from all over Europe. The size of the vacuum vessel is 2.96m in the major radius and 2.1 x 1.25m in the minor radius, and the toroidal magnetic field is smaller than other large tokamak devices, but the plasma current has been increased to 7MA, and the plasma performance has been steadily improved. The project is scheduled to be completed by 1995, and the final experiment will actually use tritium to demonstrate thermonuclear fusion reaction. jet |
ECにおいて共同で開発された,トカマク型核融合試験装置の略称。 EC共同出資で,イギリス,カラム研究所 (オックスフォード郊外,アビングドン) において開発・建設された。 1983年よりプラズマ核融合実験運転を開始している。日本の JT-60,アメリカの TFTR,ロシアのT-15とともに世界の4大トカマクと呼ばれ,ブレークイーヴン条件を目指して,成果を上げている。開発は,EC加盟国の共同運営でユーラトムが行ない,研究者は全ヨーロッパから集められている。真空容器の大きさは大半径 2.96m,小半径は 2.1× 1.25mで,トロイダル磁界は他の大型トカマク装置より小さいが,プラズマ電流を 7MAと大きくし,プラズマの性能も確実に上昇している。 95年までにプロジェクトを終了する予定で,最終実験では,実際に三重水素を使用し,熱核融合反応を実証する。
