Korea’s artificial sun set a record after running at 100 million degrees for two seconds


South Korea’s artificial sun has set a new world record after succeeding in maintaining high-temperature plasma for 20 seconds with ion temperatures in excess of 100 million degrees (Celsius).

On November 27, the KSTAR Research Center at the Korea Institute of Fusion Energy (KFE) announced a joint research project with Seoul National University (SNU) and Columbia University in the United States.

It was successful in continuous operation of the plasma for 20 seconds with an ion-temperature in excess of 100 million degrees. The voice sounds.

The milestone has been designed as an important step in the quest to generate electricity through nuclear fusion.

Si-Wu Yu, director of the KSTAR Research Center at KFE, told Phys.org, “The technologies required for the long operation of 100 million-plasma are the key to the realization of fusion energy, and KSTAR’s success in maintaining high temperatures. Plasma for 20 seconds will be a turning point in the race to acquire technologies for long high-performance plasma operation, which is an important component of a commercial nuclear fusion reactor in the future. “

Yong-su Na, professor in the Department of Atomic Engineering, who is conducting the research jointly, said: “The success of the Castorium experiment in long, high temperature operation brings us one step closer by overcoming some of the drawbacks of the ITB mode. For the development of technologies for the realization of nuclear fusion energy. “

Dr. of Columbia University Young-Seok Park who contributed to the creation of high temperature plasma: “We are honored to be involved in such a significant achievement made at KSTB.

“The 100 million-degree ion temperature achieved by enabling efficient core plasma heating for such a long period demonstrated the unique potential of the superconducting KSTAR device, and accepted it as a compelling basis for high-performance, steady-state fusion plasm Will be done.”

The new goal of KFE is to maintain the operation for 300 seconds until 2025. It explained: “A 300-second period means being able to control the instability of nuclear fusion-based power generation.

“We are going to continue our challenge to realize nuclear fusion energy, which is a goal of the entire human race.”

KFE President Suk Jeu said: “I am very happy to announce the new launch of KFE as an independent organization in Korea. KFE will continue its tradition of doing challenging research to achieve the goal of mankind.” : Attainment of nuclear fusion. Energy. “
