Physicists were able to heat the plasma inside the HL-2M device to 150 million degrees Celsius.
In southwest China in Chengdu city launched a new-generation HL-2M thermonuclear device, which experts called “artificial sun”. This is reported by Xinhua.
“Commissioning HL-2M type tokamak (toroidal chamber with magnetic coils) indicates China’s global leadership in the field of controlled nuclear fusion,” – said in the message.
The “Artificial Sun” will be used to study clean energy. The tocamac is a tire-shaped vacuum chamber in which a heated plasma is rotated by a magnetic field. The HL-2M uses tritium and deuterium ions as fuel. They are injected into the device for plasma production and controlled nuclear synthesis.
Xu Min, director of the Institute of Thermonuclear Technology of the Southwestern Academy of Physics, part of China National Nuclear Corporation, said that HL-2M exceeds similar Chinese developments in terms of basic parameters.
Compared to the “predecessor” of HL-2A, HL-2M is more compact in size. Physicists have successfully heated the plasma inside it to 150 million degrees Celsius, which is almost 3 times higher than in HL-2A.
At the same time, the scientists managed to maintain the mode of improved plasma retention for 10 seconds. For comparison, in similar projects in other countries of the world this index is less than 1 sec.
At the end of July, assembly of the ITER thermonuclear reactor started in France. All works are planned to be completed by 2025.
