Abstract: There are 8 sets of the unmovable limiter and 1 set of the moveable limiter in HL-2M tokamak, in 
order to protect the vacuum vessel and its in-vessel components. Besides, the moveable limiter would also provide 
the different plasma configurations for HL-2M physics experiments. Based on the operation requirements of 
HL-2M device, the moving distance of the moveable limiter must be larger than 120 mm, and its moving 
precision need to below 0.1mm. During the assembly of HL-2M limiter system, the laser tracker was used to meet 
the high accuracy requirement, and its assembly results show that the installation tolerance of the plasma facing 
components on the limiter is less than 0.5mm. The first plasma operation experiment results of HL-2M tokamak 
show that all of the limiter components operate well. 

Key words:  HL-2M tokamak, Limiter, Plasma
