对JT-60托卡马克进行了改造，将原外单零真空室和极向场线圈改为大D形截面。新容器的基本尺寸允许6 MA的等离子体，70至100 m3的体积和1.4至1.7的垂直伸长。该船的设计沿着一个新的概念，一个连续的室在一个双层皮肤的建设。目前正在准备将气体从氢气变为氘气，这将使中性束达到40兆瓦。第一壁的设计是利用碳纤维复合材料的偏滤器和各向同性石墨的其他地区。偏滤器瓦片由水冷却，而其他区域通过传导到容器壁来冷却。
The JT-60 tokamak was modified wherein the original outer-single null vacuum vessel and poloidal field coils, were exchanged with those of large dee-shaped cross sections. The basic dimensions of the new vessel allows plasmas of 6 MA, 70 to 100 m3volume and vertical elongations of 1.4 to 1.7. The vessel was designed along a new concept of a continuous chamber in a double skin construction. Change of the gas to deuterium from hydrogen is being prepared and will enable neutral beams of 40 MW. The first wall was designed to utilize carbon fiber composite for the divertor and isotropic graphite for the other regions. The divertor tiles are cooled by water, while the other regions are cooled by conduction to the vessel wall.
