It is the operational limit of normal-conducting device* and it was difficult maintain a stable plasma state in the fusion device at such high temperatures for a long time. ( Log Out /  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 artificial sun, named K-Star (Korea Superconducting Tokamak Advanced Research), is a breakthrough in physics because it set a new world record for the longest duration of maintaining a stable high-temperature plasma. In order to recreate fusion reactions in the sun on the earth, to create a plasma state where ions and electrons are separated, hydrogen isotopes must be placed inside a fusion device such as KSTAR and the ions must be heated and maintained at high temperatures. ( Log Out /  The Korea Superconducting Tokamak Advanced Research(KSTAR), a superconducting fusion device also known as the Korean artificial sun, set the new world record as it succeeded in maintaining the high temperature plasma for 20 seconds with an ion temperature over 100 million degrees. ( Log Out /  By. The 100 million-degree ion temperature achieved by enabling efficient core plasma heating for such a long duration demonstrated the unique capability of the superconducting KSTAR device, and will be acknowledged as a compelling basis for high performance, steady state fusion plasmas.”. In this device, the isotopes of hydrogen are brought to a plasma state in order to separate the ions from the electrons while maintaining the whole at high temperatures.

In its 2018 experiment, the KSTAR reached the plasma ion temperature of 100 million degrees for the first time (retention time: about 1.5 seconds). The final goal of the KSTAR is to succeed in a continuous operation of 300 seconds with an ion temperature higher than 100 million degrees by 2025. KSTAR, also known as the Korean Superconducting Tokamak Advanced Research reactor, is a superconducting fusion device. Published. In addition, the institute is spearheading a joint effort to open the era of nuclear fusion energy in the mid-21st century through active participation in the ITER Project. KSTAR, the Korean artificial sun sets a new record. The ‘artificial sun’—a superconducting fusion device known as KSTAR (Korea Superconducting Tokamak Advanced Research) — was used by a team of South Korean physicists for the experiment, according to reports, reports India Today.

Aims to continuously operate high-temperature plasma over the 100-million-degree for 300 seconds by 2025, NATIONAL RESEARCH COUNCIL OF SCIENCE & TECHNOLOGY. KFE President Suk Jae Yoo stated, “I am so glad to announce the new launch of the KFE as an independent research organization of Korea” “the KFE will continue its tradition of under-taking challenging researches to achieve the goal of mankind: the realization of nuclear fusion energy,” he continued. Researchers re-created the fusion reactions on the moon with the help of hydrogen isotopes that were placed inside the KSTAR which created a plasma state where ions and electrons were separated, heating ions at extreme temperatures and maintaining it too. Korea’s ‘artificial sun’ KSTAR sets world record in plasma operation of. By comparison, the KSTAR was able to achieve a temperature of over 6.6 times more than that of Sun’s. “The success of the KSTAR experiment in the long, high-temperature operation by overcoming some drawbacks of the ITB modes brings us a step closer to the development of technologies for realization of nuclear fusion energy,” added Yong-Su Na, professor at the department of Nuclear Engineering, SNU, who has been jointly conducting the research on the KSTAR plasma operation.
