The KSTAR project is being implemented by the Korea Thermonuclear Energy Institute (KEF) in cooperation with the Seoul National
In 2019, the plasma confinement time was 8 seconds. And now the researchers working at KSTAR have reported a new record - they were able to hold high-temperature plasma for 20 seconds.
Such a high temperature is needed to createartificial thermonuclear reactions - exactly the same as those occurring on the Sun. Isotopes of hydrogen are placed inside a special thermonuclear device, they recreate the state of the plasma on the star. In it, ions and electrons are separated, while the task of the ions is to give off heat and to be stable at very high temperatures.
In order to achieve this balance, scientists used various thermonuclear devices, and they managed to achieve a temperature rise of up to 100 million degrees.
The success of the KSTAR experiment in the long-termhigh-temperature operation by overcoming some of the disadvantages of ITB modes brings us one step closer to the development of technologies for the implementation of nuclear fusion energy.

Experiment details scientists promise to presentnext spring. Tests at KSTAR will continue until 2025. Their ultimate goal is to reach plasma temperatures above 100 million degrees and hold it for 300 seconds.
