tungsten Copper Components help China’s ‘Artificial Sun’ Break Record

Tungsten copper components help China's 'artificial sun' break the world record. China's Experimental Advanced Superconducting Tokamak (EAST) nuclear fusion experimental device, a major national scientific and technological infrastructure, has achieved a breakthrough, achieving a repeatable 101-second plasma operation of 120 million degrees Celsius and a 20-second plasma operation of 160 million degrees Celsius, creating a new world record.

The Tokamak devise is located at the Hefei Institutes of Physical Science of the Chinese Academy of Sciences. It is designed to replicate the nuclear fusion process that occurs naturally in the sun and stars to provide almost infinite clean energy through controlled nuclear fusion, which is often dubbed the 'artificial sun'.

The experiment of EAST is part of the International Thermonuclear Experimental Reactor (ITER) facility, a global big science project second only to the International Space Station in size, and is being jointly constructed by China, the EU, India, Japan, South Korea, Russia and the US.

This plasma operation is the first time that the EAST device has adopted all-metal active water-cooled first wall, high-performance tungsten divertor, steady-state high-power wave heating, precise plasma configuration control, and a series of key technologies that must be adopted in future fusion reactors for the first time in the world.

Among them, the high-performance tungsten divertor is considered to be one of the most difficult components to develop and manufacture in the field of nuclear fusion. Antai Technology has broken through a series of key technologies in the research and manufacture of composite parts of nuclear fusion tungsten divertor, and is in the leading position in the world.

The company's EAST lower divertor research team has overcome a series of difficulties such as new technology, difficult and tight delivery, and completed the delivery of all products in March 2021, ensuring the installation and operation of the EAST lower divertor and the achievement of world records.

At present, the development and production of the core tungsten copper composite parts of the 'artificial sun' upper/lower divertors that have been put into use worldwide, and the tungsten copper parts of the divertors of the French WEST device that are being installed are all completed by Antai Technology.

With its strong technological innovation strength, China Antai Technology serves the country's major scientific engineering installations and promotes the progress of the human energy revolution.
