South Korea’s artificial Sun burns at 100 million degrees for 20 seconds, sets new world record
This was the first time a fusion device sustained plasma for more than 10 seconds. More than 250 such tokamak devices have been built so far, but none have been able to achieve this feat thus far.
KSTAR fusion device (Wikipedia)
South Korean scientists set a new world record for high-temperature sustained plasma using a superconducting fusion device on November 24.
The Korea Superconducting Tokamak Advanced Research (KSTAR) device, commonly referred to as South Korea’s artificial sun, burnt for 20 seconds straight at an ion temperature of more than 100 million degrees Celsius.
