Experimental Advanced Superconducting Tokamak

Common card · No. 247920

The Experimental Advanced Superconducting Tokamak (EAST), also known as HT-7U (Hefei Tokamak 7 Upgrade), is an experimental superconducting tokamak magnetic fusion energy reactor in Hefei, China. Operated by the Hefei Institutes of Physical Science conducting its experiments for the Chinese Academy of Sciences, EAST began its operations in 2006. EAST is part of the international ITER program after China joined the initiative in 2003 and acts as a testbed for ITER technologies. On January 20, 2025, it sustained plasma for 1066 seconds. EAST was the first tokamak to utilize superconducting coils to establish both the toroidal and poloidal magnetic fields.
