摘　　要：HL-2M装置设计有8套固定极向限制器和1套活动极向限制器,其主要功能是进一步加强保护真空室及其内部件,同时活动限制器还将提供不同孔栏位形用于等离子体物理实验。根据HL-2M装置总体运行需求,活动限制器结构设计可移动有效距离为120mm,活动限制器移动精度可控制在±0.1mm以内。基于激光跟踪仪测量方法对HL-2M装置限制器系统完成了高精度的安装,限制器的面向等离子体关键位置安装精度优于±0.5mm,通过初始等离子体放电实验表明其运行状态均正常。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.
