摘　　要：中国环流器二号A装置(HL 2A)(设计指标:大半径1.65m、小半径0 4m、环向磁场2 8T、环向等离子体电流480kA)是我国已建成的第一个偏滤器托卡马克实验型磁约束聚变装置。HL 2A装置的首要研究目标是利用其独特的大体积极向偏滤器在高参数等离子体条件下开展与偏滤器位形运行有关的研究。本文总结了HL 2A装置工程设计、制造与安装、工程调试等研制的主要内容和关键技术。工程调试和初步物理实验的结果表明:HL 2A装置的主要工程参数和性能已具备开展物理实验的条件,并已成功地运行于偏滤器位形。2003年11月底,HL 2A装置获得等离子体电流168kA,等离子体存在时间920ms,等离子体线平均密度1.7×1019m-3,环向磁场1 4T,极限真空度为4.6×10-6Pa。The HL-2A tokamak (design values:major radius 1.65m,minor radius 0.4m,plasma current 0.48MA and toroidal field 2.8T) is the first tokamak with an operating divertor in China.It is characterized by a large closed divertor chamber.This unique feature will make significant contributions to enhance our understanding of complex divertor plasma physics and to help validating divertor physics modelings.The engineering design,development,testing and commissioning of the HL-2A tokamak are described in this paper.Preliminary results show that the HL-2A tokamak has been successfully operated in the divertor configuration.The major parameters:plasma current I_p=168kA,toroidal field B_T=1.4T,plasma line average density n_e=1.7×10^(19)m^(-3),limiting vacuum p_v=4.6×10^(-6)Pa,were achieved at the end of 2003.
