Most powerful magnet created by the US moves to France

On July 15th, the world’s most powerful magnet, constructed in the United States, has reportedly been shipped to the International Fusion Laboratory (ITER) in Paris, France. The fusion power generation of ITER is also known as the artificial sun since it mimics the mechanics of the energy production of the sun. It is the world’s most powerful magnet and is expected to be the heart of this artificial sun.

 

The ITER is an international research and development project that specializes in the demonstration and commercialization of nuclear fusion energy. With the cooperation of multiple nations including South Korea, the EU, the United States, Japan, and Russia, the ultimate goal of ITER is to assemble the components made by different countries at the ITER construction site in France by 2025. According to General Atomic, an energy and defense corporation in the US, the researchers have finally completed the central electromagnet after 10 years of development. It is expected to become a key component of the ITER.

 

The magnet acts as a means of pushing the fusion materials from both sides to prevent the surrounding devices from melting during the process of high energy production. This occurs at 100 million degrees Celsius as light atoms fuse into heavier nuclei, generating as much energy as the decrease in their mass. This central superconducting electromagnet weighs 1,000 tons and consists of a niobium-tin superconducting coil with a total length of 43 kilometers. It enters a container that can withstand up to twice the thrust or force generated when a space shuttle takes off to be safely delivered to the ITER site. 

 

Experts assert that the transfer of the central superconducting electromagnet would be sequentially done by dividing it into six modules. The first module has already been shipped and is on its way to the ITER construction site in southern France and is expected to arrive in late August.

 

The ITER plans to complete the construction of a fusion reactor by 2025, and start full-scale commercial development with the production of energy surpassing the input energy by 2030. With the successful development of the ITER’s artificial sun, experts look forward to the commercialized use of the nuclear fusion energy generated by the plasma condition of the artificial sun which would then become widely used as an everlasting source of energy to produce electricity.
