The construction of my country’s large scientific device “Kuafu” has ushered in important progress: one of the 19 subsystems has passed the acceptance and reached the international leading level – Passionategeekz

Passionategeekz June 18th news, according to CCTV News today, the Hefei Institute of Material Science, Chinese Academy of Sciences, said that one of the 19 subsystems of the “Kafu” of the national major scientific and technological infrastructure fusion reactor host key system comprehensive research facility, the low-clutter current drive system, passed the expert group test and acceptance today (June 18th).The overall system performance reaches the international leading level。

The low-clutter current driving system uses electromagnetic waves in the centimeter band to allow waves to interact with particles to obtain directional momentum for electrons, drive plasma current and heat plasma. This system is like a “microwave stove”. When operating, the maximum power of the system is equivalent to 4,000 microwave ovens with 1,000 watts of power work simultaneously.

This acceptance system has been implementedThree project goals,Right now

• Center frequency 4.6 GHz,

• The maximum total output power of microwave source is 4 MW,

• The running pulse length setting target is 100 seconds, but 1592 seconds were reached in the test.

In order to achieve these three goals, the project team took five years to develop and solved the problemCoupled antenna design for reactors, long-distance low-loss power transmission, reliable and safe operation of multi-tube parallelKey technologies have been implementedDomestic system。

The successful acceptance of the low-clutter current drive system marks the completion of the complete process from design optimization, pre-research verification, processing and manufacturing, to testing and acceptance, and has laid a solid scientific and technological foundation for the design and development of the fusion reactor heating system. Related technologies can be expanded to be used in microwave heating, wireless communication, medical and health care, electronic technology and other fields.

“Kuafu” is named after a hero who chases the sun in ancient Chinese mythology. Its scientific name is “Comprehensive Research Facility for Critical Systems of Fusion Reactor Hosts (CRAFT)”, is a major national scientific and technological infrastructure project approved in the 13th Five-Year Plan. It started construction in December 2018 and is expected to be fully completed by the end of 2025.

According to Passionategeekz, nuclear fusion is a reaction that occurs inside the sun and can release huge energy. If this reaction can be simulated on Earth, human energy problems can be solved. China has begun to explore nuclear fusion energy since the 1970s, and has built a number of experimental devices such as “East Super Circuit (EAST)” and “China Circuit Devices”, and has achieved many major results.
