摘要/Abstract

摘要： 使用EFIT程序设计了HL-3装置雪花偏滤器位形，研究了雪花位形对HL-3装置极向场(PF)线圈电流变化的敏感性。研究发现：当PF线圈电流变化达1%时，标准雪花偏滤器转变为雪花加位形或是雪花减位形；当PF线圈电流变化超过8.8%时，雪花减位形在大偏离度下能够获得平衡位形，而雪花加位形难以获得收敛结果。

Abstract: The configuration of the HL-3 snowflake divertor by using the EFIT program was designed, and the sensitivity of the snowflake configuration of HL-3 tokamak on the individual lower poloidal field (PF) coil current was studied. It was found that when the individual lower PF coil current only changes by 1%, the standard snowflake divertor immediately changes to a snowflake plus configuration or snowflake minus configuration, and when the individual lower PF current changes above 8.8%, the snowflake minus configuration can reach a equilibrium configuration with a large deviation, while the convergence result is difficult to be obtained under the snowflake plus configuration.
