Abstract: The physical design of magnetic measurement system for plasma discharge on HL-2M tokamak is 
introduced, including the designs of magnetic probes, magnetic flux loop and current measurement system. 
Through the typical discharge configuration parameters of HL-2M tokamak, the poloidal layout and effective area 
of magnetic probes, the poloidal layout of magnetic flux loop and the mutual inductance of Rogowski coil for 
measuring plasma current were designed. At present, the HL-2M tokamak has completed the first plasma 
discharge. Each subsystem achieves its measurement target.

Key words: HL-2M tokamak, Magnetic measurement, Physical design 

摘要： 介绍了 HL-2M 装置上满足等离子体放电的磁测量系统的物理设计，主要包括磁探针、磁通环以及
电流测量系统的设计。通过 HL-2M 装置典型的放电位形参数对磁探针的极向布局、有效面积，磁通环的极向布
