HL-2A

Published on 17 November 2017
    1. HL-2A is a medium-size copper-conductor tokamak put into operation in 2002, with the major and minor radii of 1.65 meters and 0.4 meters respectively, and the operation plasma current up to  480 kA. The research programme of HL-2A aims at fundamental fusion plasma physics studies in relation to ITER and fusion reactor. Since its first operation, the heating has been gradually enhanced to 4 MW of NBI, 5MW of ECRH and 2 MW of LHCD. More than 60 diagnostics have been developed on HL-2A, such as HCN interferometer, Thomson scattering, microwave Doppler reflectometry, etc. Flexible plasma fueling techniques have been installed, such as LFS and HFS pellet injection, supper molecular beam injection (SMBI), as well as gas puffing, to facilitate plasma control and physics study. Over the years, HL-2A has gained a world reputation due to its significant contribution to the fusion technology development and physics research in many fields.
