Progress of HL-2A physical experiments

This paper presents the status of the HL-2A tokamak and its auxiliary systems, and the highlights of the experiments on magnetic fusion plasma in HL-2A. In particular, China’s first high confinement mode (H-mode) operation has been achieved on this device which is an important milestone in the history of magnetic fusion research in China. Due to its good accessibility, innovative fueling technologies and many advanced diagnostics with high spatiotemporal resolution, an amount of key issues on magnetic fusion plasma have been investigated and a series of innovative achievements have been obtained. They will provide important scientific and technical basis for ITER operation and design of future fusion DEMO.
