Chinese scientists broke the record by reaching a plasma temperature of 120 million degrees Celsius for 101 seconds and 160 million degrees Celsius for 20 seconds. According to the researchers, this is a major step towards the reproduction of fusion, which naturally proceeds on the sun and other stars.
The record was broken at the tokamak EAST (Experimental Advanced Superconducting Tokamak), located at the Hefei Institute of Physical Sciences. Previously, scientists working on the EAST project managed to achieve a temperature of 100 million degrees Celsius for a hundred seconds. At the same time, achieving plasma temperatures above 100 million degrees Celsius is one of the key challenges in nuclear fusion. It is believed that the temperature in the core of the Sun is 15 million degrees, which means that the plasma in the tokamak is several times hotter than the Sun.
According to scientists, it will take another 30 years to develop fusion systems before the technology can be applied in practice.
The EAST experiment is part of the International Thermonuclear Experimental Reactor (ITER) project, which involves China, India, the EU, Russia, the United States and other countries.
