of Records
  • Researchers in the world participate the JFT-2M experiments. Domestically, cooperative experiments are going on widely with researchers of universities and national institutes.
  • Many pioneering experiments were performed in the nuclear fusion research.
    • Provision of physics data for the ITER design
    • Preliminary experiments for JT-60
  • The Emperor Showa visited the JFT-2 device, which was the previous device before remodelling.
  • The DC generator operating the device is largest in the world, which is registered in the Guinness Book of Records in 1997/1998. This DC generator was manufactured, miraculously undamaged in the Great Hanshin-Awaji Earthquake.
