HL-1 TOKAMAK (1984-1992) |
|
|
 |
 |
HL-1 was the first medium-sized tokamak (R=1.02m, a=0.20m) in China,
which was designed and constructed by SWIP in 1984. It was awarded the
first class prize in National Science and Technology Progress in 1987.
HL-1 Tokamak consisted mainly of iron transformer, toroidal, poloidal
and vertical field coils, inner (S.S. Bellow) and outer vacuum vessels
(thick copper shell). The L-H transition induced by a biased electrode
and the improved ohmic confinement were achieved during the HL-1
Experiment. |

|
Auxiliary heating and current drive (ECRH and LHCD), and pellet injection had been performed. |
