"In the long-pulse static H-mode, a big challenge is particle control and heat exhaustion. Solving these problems allowed long-pulse discharge to extend to 100 seconds, which is a new century record and also a new millstone for EAST."

China's Experimental Advanced Superconducting Tokamak (EAST) has achieved 101.2 seconds steady-state high-confinement (H-mode) operations, the Institute of Plasma Physics of the Chinese Academy of Sciences announced on Tuesday.

The device, with a height of 11 meters, diameter of eight meters and weight of 400 tons, is aimed at providing clean energy by inducing the deuterium and tritium in seawater to form nuclear fusion under high-temperature conditions in order to provide clean energy. After years of research, EAST now can maintain a sustained H-mode plasma under a electron temperature of 50 million Kelvins, which broke its record of maintaining for 60 seconds.

"In the long-pulse static H-mode, a big challenge is particle control and heat exhaustion. Solving these problems allowed long-pulse discharge to extend to 100 seconds, which is a new century record and also a new millstone for EAST," said Gong Xianzu, person in charge of EAST.

The steady-state H-mode operation is a basic operational mode of International Thermonuclear Experimental Reactor (ITER) as well as a key scientific issue for reactors in the future. Scientists said the breakthrough of the EAST would lay a solid technical foundation for China's next generation nuclear fusion device and exploitation and development of international nuclear fusion clean energy.
