‘Artificial Sun’ on Earth reaches record 100 million degrees temperature

Korean Artificial Sun – KSTAR Fusion Reactor – Sets New World Record

In comparison to the year 2019, this time the sun on the earth operated 8 seconds more plasma.

KSTAR reached a plasma temperature of 100 million C the year before that, but only maintained it for around 1.5 seconds. We're still talking about seconds of production for now, but the Korean superconducting search device Tokamak Advanced Research (KSTAR) recently set a world record by keeping its plasma at an ultra-high temperature of 180 million degrees Fahrenheit for 20 seconds - almost twice the time of a second.

Notably, fusion devices such as the KSTAR, are used to understand fusion reactions that occur inside the Sun.

The device has set a new world record for fusion when compared to the core of the sun, which burns at only 15 million degrees Celsius. None of them broke the limits of maintaining the activity for 10 seconds or more.

It succeeded in continuous operation of plasma for 20 seconds with an ion-temperature higher than 100 million degrees.

As per another report, Si-Woo Yoon, Director, KSTAR Research Center said, "The technologies required for long operations of 100 million plasma are the key to the realisation of fusion energy, and KSTAR's success in maintaining the plasma of high temperature for 20 seconds will be a major turning point in the race to secure technologies for the long-term operation of high-performance plasma, a critical component of a commercial nuclear fusion reactor in the future". China subsequently claimed a new record in 2017 with its Experimental Advanced Superconducting Tokamak (EAST), managing to maintain plasma at a similar temperature for 102 seconds.

In order to retain the ions, it is essential to maintain extremely high temperatures.

Dr. Young-Seok Park of Columbia University who contributed to the creation of the high temperature plasma said "We are honored to be involved in such an important achievement made in KSTAR". Its goal is to demonstrate that it is possible to build a device that can release more energy through nuclear fusion (in a controlled manner), than it takes to create the condition for fusing light atoms in the first place. But, none of those devices could last 10 seconds.

In addition to the success in high temperature plasma operation, the KSTAR Research Center conducts experiments on a variety of topics, including ITER researches, created to solve complex problems in fusion research during the remainder of the experiment period.

This is an important step towards the ultimate goal of maintaining plasma with an ion temperature of over 100 million °C for five minutes by 2025. After carrying out research at annex institutes, the KFE recently became an independent agency. 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.
