HL-1M足HL-1的改进型圆形截面托卡马克装置,真空室大环半径r=102 cm,小半径r=32 cm,内表面积13 m2,有效体积2 m3;装置内部设置了经二次纯化的SMF-800石墨保护板,总重量40 kg,表面积3.6 m2,内壁表面覆盖率约6.5％[1],此外大部分是裸露的不锈钢壁。 HL-1M装置自1994年启动到2000年为止的7年实验运行中,系统地开展了 HL-1MH HL-1 modified circular cross-section tokamak device, the large radius of the vacuum chamber r = 102 cm, small radius r = 32 cm, the inner surface area of ​​13 m2, the effective volume of 2 m3; Secondary purification SMF-800 graphite protective plate, the total weight of 40 kg, a surface area of ​​3.6 m2, the inner wall surface coverage of about 6.5% [1], in addition to the majority of exposed stainless steel wall. The HL-1M unit has been systematically implemented in a seven-year pilot operation that started in 1994 up to 2000
