Recently, the world’s first fully high-temperature superconducting Tokamak device, developed and constructed by Energy Singularity, known as “HH70,” has successfully achieved first plasma. HH70 has conducted discharge experiments based on two types of pre-ionization methods: localized helical magnetic flux injection (electron gun) and ion cyclotron heating (ICRF), and has successfully obtained the first plasma. The toroidal magnetic field (B0) of HH70 is 0.6 Tesla, with a plasma major radius of ...
