Break-even plasma test facilities JT-60; The Significance in the history of technology development

Kurihara, Kenichi

Breakeven plasma test facilities JT-60, as a large scale electrical device, has been developed in accordance with great technological advances of electrical applications such as power electronics, large energy storage with a motor generator, high power microwaves, high energy neutral beam, etc. JT-60 demonstrated efficient and continuous nuclear fusion reactions as well as a break-even plasma in a tokamak, and opened up the prospect of a fusion power plant in the future. In this article, the significance of JT-60 is considered from the viewpoint of the history of technology development in electrical engineering.
