China's "Artificial Sol" is ready to launch a thermonuclear reaction

An experimental version of superconducting tokamak has reached a new temperature record at the Institute of Physical Sciences of the Chinese Academy of Sciences in Hefei. Scientists have warmed plasma to 100 million degrees. This means that the device known as "Artificial Sol" generated informally 6 times more heat than the core of the Sun, which reaches only 15 million Kelvin.

The dream of nuclear physics scientists – to get a controlled thermonuclear reaction and create an inexhaustible source of energy – took a step forward. There may be no higher temperature records – the current indicators are enough to start trying to connect the nuclei of hydrogen atoms and trigger a chain reaction. Specifically, this is the calculated minimum value – and now, beyond that limit, you can start the bolder experiments.

The device used a power of more than 10MW, and when the researchers optimized theoretical calculations and simulation of different heating techniques and advanced plasma control, the plasma energy increased to 300 kJ. The electron temperature in the plasma has increased by more than 100 million degrees. Dozens of factors limit the recurrence of the thermonuclear reaction in the Earth's solar core. Since we can not restore all conditions within the star, we must look for other ways. The Tokamak is designed to contain the highest plasma energies controlled by magnetic fields much higher than the Sun. Only under such conditions here on Earth can a self-controlled controlled thermonuclear reaction be activated.
