Sun Made in China Sets New Record, Lasts Longer Heat


The Experimental Advanced Superconducting Tokamak (EAST) fusion energy reactor set a new world record this week. The sun made in China runs for 1,056 seconds at high plasma temperatures, the longest duration for the fusion energy reactor so far.

Earlier in May, EAST set a record run for 101 seconds at a temperature of 120 million degrees Celsius. The new record was reached after a team of scientists announced that a new round of testing would be carried out by the Institute of Plasma Physics under the Chinese Academy of Sciences (ASIPP).

The institute, located in Hefei, Anhui Province, east China, has supplied electricity more than 10,000 times since the inauguration of phase II of EAST in 2011.

Designed to mimic solar-like fusion reactions using hydrogen and deuterium gases as fuel, EAST will unlock insights into plasma physics research that is critical to building industrial-sized reactors, to produce clean energy.

Fusion energy is considered the ideal "ultimate energy" for a carbon-neutral energy future because hydrogen and deuterium gases are abundant in the ocean.

The institute has also collaborated with high-emission companies to help them achieve carbon neutrality, according to ASIPP director Song Yuntao.

To date, EAST has hit all three targets separately: a current of 1 million amperes, a duration of 1,000 seconds, and a temperature of 100 million degrees Celsius. The tokamak's final mission is to hit all of these targets in one go.
