South Korea's entry on creating their own artificial Sun has finally paid off. In recent reports, the organization announces beating the world record of maintaining the high temperature plasma for 20 seconds with an ion temperature over 100 million degrees (Celsius).
Koreans create its own version of Sun
Could humans create their own star? Apparently, yes.
In a new report from Phys.org, the South Korean organization called KSTAR Research Center at the Korea Institute of Fusion Energy (KFE) breaks the world record of maintaining the longest high temperature plasma for about 20 seconds with its artificial sun called Korea Superconducting Tokamak Advanced Research (KSTAR).
"The technologies required for long operations of 100 million- plasma are the key to the realization of fusion energy, and the KSTAR's success in maintaining the high-temperature plasma for 20 seconds will be an important turning point in the race for securing the technologies for the long high-performance plasma operation, a critical component of a commercial nuclear fusion reactor in the future," said Director Si-Woo Yoon of the KSTAR Research Center at the KFE.
This device is a superconducting fusion that imitates how the Sun is like on space (especially in its heat performance). In 2018, KSTAR only reaches this heat for about 1.5 seconds long. Thus, explaining the extended time it developed over the years.
As also compared, most of the fusion devices being developed today only reached 100 million degrees for only 10 seconds.
100 million degrees is as hot as the core of the real Sun-- which is the hottest part of the star.
How to create fusion reactions?
Based on the experiment, the KSTAR will be used to create a plasma state where ions and electrons are separated, and ions must be heated and maintained at high temperatures.
Hydrogen isotopes will be put inside the fusion device, in order for this to happen.
China's own version of Sun
Just like South Korea, the Chinese government is also developing its artificial sun fusion device that is nuclear-powered. However, instead having 100 million degrees celsius, China has experimented to reach 150 million degrees celsius.
This is equivalent to 10 times hotter than the core of the real Sun. So far, though, the time duration of this device is still not announced.
