Chinese company Energy Singularity has successfully launched a high-temperature superconducting tokamak reactor, achieving plasma generation. This marks a significant breakthrough in nuclear fusion, paving the way for generating immense amounts of energy.
Experiments conducted on Energy Singularity’s HH70 reactor involved discharge tests using two pre-ionization methods: localized injection of spiral magnetic flux (electron gun) and ion-cyclotron resonance heating (ICRF). These experiments successfully generated plasma. While the company has not disclosed the exact temperature achieved, it is known that the toroidal magnetic field of the HH70 is 0.6 tesla, and the major radius of the plasma is 0.75 meters.
The magnetic system of the HH70 comprises 26 high-temperature superconducting magnets. According to available information, the localization level exceeds 96%, which effectively eliminates China’s reliance on other countries for advancements in nuclear fusion technology.
Though specific details on the energy output of the HH70 are not yet available, this achievement stands as the world’s first confirmation of the viability of the fusion concept.
