At 9 pm on the evening of April 12, China’s all-super conducting tokamak nuclear fusion experimental device (EAST), better known as the “artificial sun”, set a new world record, successfully remaining stable for 403 seconds. state high-restriction mode plasma operation was achieved. It is of great importance to address the frontier physical problems of future fusion reactors, to improve the economy and feasibility of nuclear fusion energy, and to accelerate the realization of fusion power generation.
All life on earth requires energy from the sun. The reason why the Sun emits light and heat is because of the nuclear fusion reaction inside. The raw materials for nuclear fusion energy are highly abundant on Earth, and the emissions are non-polluting. If the “Sun” is harnessed to generate electricity, Can be built, mankind is expected to achieve energy independence. But making a practical “artificial sun” is a huge challenge. For this, scientists around the world have been working hard for more than 70 years .
As a key national scientific and technological infrastructure, EAST has a nuclear fusion reaction mechanism similar to that of the Sun. On the evening of April 12, after more than ten years of intensive research, EAST successfully conducted a stable- Achieved state high-impedance mode plasma operation, breaking the world record of 101 seconds set in 2017.
