After more than 8 hectic years, the assembly of the JT-60SA<\/a><\/strong> fusion device is finally complete. This achievement is a major milestone<\/strong> that brings the world\u2019s currently largest superconducting<\/strong> tokamak <\/strong>ready for operation. <\/p>\n

EUROfusion<\/strong><\/a> and the Fusion Energy Forum of Japan<\/strong> have led the JT-60SA project to build a tokamak able to confine 100 million degree<\/strong> plasmas. The facility of the Japanese-European tokamak is located at Naka<\/strong> (Japan) under the auspices of the National Institute for Quantum and Radiological Science and Technology<\/a> (QST) which has operated various tokamaks such as JT-60<\/strong> or JT-60U<\/strong> since 1985.<\/p>\n

JT-60SA will start its operation later this year<\/strong> diving into the study of hydrogen and deuterium plasmas in support to ITER<\/a> and DEMO<\/a> preparation. The mission is to produce steady-state scenarios at high beta and density<\/strong> that will make key contributions to the understanding of plasma physics. During ITER’s operation, JT-60SA will have the role of an ITER-satellite tokamak<\/strong> due to its relevance for the fusion energy roadmap<\/a>.<\/p>\n

JT-60SA is a major engineering achievement on its own. Its central solenoid is one of the largest coils in the world.<\/strong> With 2.1m in diameter, 9.5m in height and 100 tons in weight, it is able to produce a 10T magnetic field<\/strong>. The vacuum vessel weighs ~300 tons and its diameter is 10m and its height is 6.2m<\/strong>.<\/p>\n

Regarding the components that heat the plasma, there are two neutral beam injection (NBI) methods, P-NBI<\/strong> (24 MW<\/strong> at 85 keV) and N-NBI<\/strong> (10 MW<\/strong> at 500 keV). Together with the electron cyclotron heating at 7 MW<\/strong>, they make a total 41 MW<\/strong> of heating power.<\/p>\n

These impressive features, among others, make JT-60SA one of its kind, ready to make important contributions to the realization of fusion energy<\/strong>.<\/p>\n
