1KSTAR托卡马克设计显示文摘韩国超导托卡马克(KSTAR)探索性研究项目是韩国国家聚变计划的重点项目,其主要工作是研制能稳态运行的先进超导托卡马克,为具有吸引力的聚变堆建立科学技术基础。该托卡马克的主要参数是,大半径1.8m,小半径0.5m,环向场3.5T,环向场3.5T,等离子体电流2MA,并具有强变形的等离子体横截面和双零偏滤器。最初由极向磁系统提供的脉冲长度为20s,但是通过非感应电流驱动脉冲长度可以增大到300s。等离子体加热和电流驱动系统包括中性束,离子回旋波,低杂波和电子回旋波,它们都可用于灵活的剖面控制。全套诊断设备计划用于等离子体控制和特性计算以及对物理学的了解。该项目已经完成概念设计阶段,进入到工程设计阶段。首次产生等离子体的日期确定在2002年。G.S.Lee 王尚柄2002国外核聚变2002,,2:0
2Present Status of the KSTAR Superconducting Magnet System Development显示文摘The mission of Korea Superconducting Tokamak Advanced Research (KSTAR) project is to develop an advanced steady-state superconducting tokamak for establishing a scientific and technological basis for an attractive fusion reactor. Because one of the KSTAR mission is to achieve a steady-state operation, the use of superconducting coils is an obvious choice for the magnet system. The KSTAR superconducting magnet system consists of 16 Toroidal Field (TF) coils and 14 Poloidal Field (PF) coils. Internally-cooled Cable-In-Conduit Conductors (CICC) are put into use in both the TF and PF coil systems. The TF coil system provides a field of 3.5 T at the plasma center and the PF coil system is able to provide a flux swing of 17 V-sec. The major achievement in KSTAR magnet-system development includes the development of CICC,the development of a full-size TF model coil, the development of a coil system for background magnetic-field generation , the construction of a large-scale superconducting magnet and CICC test facility. TF and PF coils are in the stage of fabrication to pave the way for the scheduled completion of KSTAR by the end of 2006.Keeman Kim H.K.Park K.R.Park B.S.Lim S.I.Lee M.K.Kim Y.Chu W.H.Chung S.H.Baek J.Y.Cho H.Yonekawa A.Chertovskikh Y.B.Chang J.S.Kim C.S.Kim D.J.Kim N.H.Song K.P.Kim Y.J.Song I.S.Woo W.S.Han D.K.Lee Y.K.Oh K.W.Cho J.S.Park G.S.Lee H.J.Lee T.K.Ko S.J.Lee 2004Plasma Science and Technology2004,6,5:0
3Current Status of the KSTAR Engineering显示文摘As there is substantial progress in the KSTAR tokamak engineering, all the major structures and sub-systems are under fabrication and in procurement phase.The vacuum vessel,port,cryostat cylinder,lid,and bellows are being rigorously fabricated in the factory.The lower part of the KSTAR such as cryostat base and gravity support has been almost finished in its fabrication.There are also great progresses and significant results in manufacturing of the superconducting magnet,including four Toroidal Field (TF) coils,lower and upper PF7 coils which are the largest Poloidal Field (PF) coils.The TF00 coil,which has been made for test and back-up of the TF magnet system,was successfully tested in the cool-down and current charging.As the fabrications and procurements of major structures have been actively proceeded,assembly works were also launched from Aug.2003.More detailed description on these status,results,and plans will be described in this paper.J.S.Bak K.Kim C.H.Choi Y.K.Oh B.C.Kim N.I.Her H.L.Yang G.S.Lee the KSTAR Team 2004Plasma Science and Technology2004,6,1:0
