HL-2M is a research tokamak at the Southwestern Institute of Physics in Chengdu, China. It was completed on November 26, 2019 and commissioned on December 4, 2020. HL-2M is now used for nuclear fusion research, in particular to study heat extraction from the plasma.^[1][2] With a major radius of 1.78 m, the tokamak is a medium-scale device. The magnetic field of up to 2.2 T is created by non-superconducting copper coils.
