The team led by Yong-Su Na benefited Modifying the internal transport barrier technologyThanks to this, scientists were able to obtain a much lower plasma density, but at the same time its temperature increased to 100 million degrees. Scientists explain that this extended the life of the entire artificial sun, which is important in the marketing process.
Interestingly, the KSTAR tokamak has been disabled for the past two years and modification work is still ongoing. Scientists replaced the carbon elements on the reactor wall with materials made of tungsten. This will directly translate into more Longer service life of the entire structure at extreme temperatures And much longer working time. The first effects of the modifications have already set new records.
– Although this is the first experiment conducted with tungsten converters, the comprehensive testing of the equipment and the preparatory campaign allowed us to quickly achieve better results than the last record, says Si Woo Yun, Director of the KSTAR Research Center. – in order to achieve KSTAR's ultimate goalHe added, “We plan to successively increase the heating power and power of the plasma driving devices, in addition to implementing the key technologies necessary to obtain long plasma operating pulses.”
Many countries around the world are currently working on making artificial suns. One of the largest projects in France is currently being implemented. A European thermonuclear reactor, ITER, is being built there and is scheduled to be ready in 2025. Tests will then begin and will continue for 10 years. Experts believe that a positive energy balance at ITER will be achieved in the first half of the 2030s. It is interesting that they are participating in the project Scientists from the Polish Academy of Sciences.
Echo Richards embodies a personality that is a delightful contradiction: a humble musicaholic who never brags about her expansive knowledge of both classic and contemporary tunes. Infuriatingly modest, one would never know from a mere conversation how deeply entrenched she is in the world of music. This passion seamlessly translates into her problem-solving skills, with Echo often drawing inspiration from melodies and rhythms. A voracious reader, she dives deep into literature, using stories to influence her own hardcore writing. Her spirited advocacy for alcohol isn’t about mere indulgence, but about celebrating life’s poignant moments.
