New Scientist A powerful plasma discharge has operated for a world record 210 seconds in an experimental French fusion reactor. The demonstration is a significant step toward the long plasma confinement times needed in a practical fusion reactor.
Physicists sustained the three-megawatt electric discharge in the Tore Supra reactor at the Association Euratom-CEA in Cadarache. During that interval, it dissipated more than 600 megajoules of energy, more than twice the previous record, also set by Tore Supra in 1996
