The Korea Superconducting Tokamak Advanced Research (KSTAR) device, commonly mentioned as South Korea’s artificial sun, burnt for 20 seconds straight at an ion temperature of quite 100 million degrees Celsius.
As against this, the core of the Sun burns at only 15 million degrees Celsius.
Notably, fusion devices like the KSTAR, are wont to understand fusion reactions that occur inside the Sun.
This was the primary time a fusion device sustained plasma for quite 10 seconds. quite 250 such tokamak devices are built thus far , but none are ready to achieve this feat so far .
Earlier, during the 2019 KSTAR Plasma Campaign, scientists were ready to maintain plasma for less than eight seconds. In 2018, physicists were ready to maintain plasma at 100 degrees Celsius for the primary using the KSTAR device. However, it had lasted just one .5 seconds.
Physics Org quoted KSTAR research facility Director Si-Woo Yoon as saying: “The technologies required for long operations of 100 million-plasma are the key to the realisation of fusion energy, and therefore the KSTAR’s success in maintaining the high-temperature plasma for 20 seconds are going to be a crucial turning point within the race for securing the technologies for the long high-performance plasma operation, a critical component of a billboard fusion reactor within the future.”
The goal of the Korea Institute of Fusion Energy (KFE) is to sustain fusion ignition for 300 seconds with ion temperature of over 100 million degrees Celsius by the year 2025.
