Q. Recently, which country has made world's first high- temperature superconducting Tokamak device 'HH70'?
Answer:
China
Notes: China has unveiled HH70, the world's first fully high-temperature superconducting Tokamak device, in Shanghai. Developed by Energy Singularity, HH70 achieved first plasma, utilizing innovative pre-ionization methods. With a toroidal magnetic field of 0.6 Tesla and a major radius of 0.75 meters, it features 26 high-temperature superconducting magnets. HH70 marks China's leadership in high-temperature superconducting magnetic confinement fusion, setting milestones as the first commercial superconducting Tokamak worldwide. Energy Singularity plans to advance with HH170, aiming for significant energy gain by 2030, cementing China's pioneering role in fusion energy technology.
