China's "artificial sun" is ready to produce a thermonuclear response.

The experimental superconducting tokamak version achieved a new temperature record at the Institute of Physical Sciences at the Chinese Academy of Sciences in Hefei. Scientists have heated plasma to 100 million degrees. This means that a device known as the "Artificial Sun" unofficially generated six times more heat than the Sun core, which explodes at just 15 million Kelvin temperatures.

The dream of nuclear physicists to achieve a controlled thermal nuclear reaction and create an endless source of energy went a step further. There may be no higher temperature record. The current indicator is sufficient to connect the hydrogen atom nuclei and cause a chain reaction. Specifically this is the minimum calculated value. Now you can go beyond that and start your boldest experiment.

The device used more than 10 MW of power and plasma energy increased to 300 kJ when researchers optimized the theoretical calculations and simulations of various heating techniques and advanced plasma control. The electron temperature of the plasma increased by more than 100 million degrees. The recurrence of thermal nuclear reactions in the solar nuclei on the Earth is limited to dozens of factors. We can not restore all the conditions inside the star, so we need to find a different path. Tokamak is designed to suppress the greatest energy in a plasma controlled by a magnetic field, much higher than the sun. Only under these conditions can self-controlled thermonuclear reactions be activated on Earth.
