摘要: HL-2A中性束注入系统(NBI)由两条束线组成,总注入功率3MW,能量45KeV-60KeV,每条束线上安装4个大功率离子源。目前,安装在第一条束线上的桶式灯丝离子源已运行5年,离子源参数完全达到了设计指标:单离子源离子束功率0. 8MW,总中性束注入功率1MW;第二条束线安装新研制的大功率射频离子源,束能量60KeV,单个离子源离子束功率1.5MW,中性束功率2MW。计划2013底第二条束线将运行。 大功射频射频离子源具有长寿命、结构简单、高电离效率、维护方便等特点成为ITER大功率中性束注入器的最佳选择,也是中性束大功率离子源的发展方向。近年来,对射频驱动高密度等离子体的产生、等离子体密度均匀性控制、射频等离子体诊断、初始等离子体产生、大功率射频传输与耦合、高压高功率高频阻抗变换器、以及涉及射频离子源工程技术等进行了研究,已经取得了一定进展:射频功率40KW,等离子体密度达到了1.2× 1018/m3,1.5MW的大功率射频离子源已经完成了工程设计,2013年初将进入调试阶段。 关键词:射频离子源;灯丝离子源; 中性束注入器

Abstract: HL-2A NBI (Neutral Beam Injection) with total beam power of 3MW is composed of two beamlines which are located at opposite of the torus in tangential direction injection. The first NBI equipped 4 bucket filament ion sources has been operated for 5 years an
摩信网d total injection neutral beam power of 1MW at energy of 45KeV has been achieved in 2011. RF ion sources with ion beam power of 1.5MW and energy of 60KeV for the second beamline is being developed and will be operated on the second beamline in the end of 2013.
RF driven plasma ion source is an important candidate for ITER NBI because of its several characteristics: long life operation, simple structure, high plasma density and easy maintenance. It becomes also trend of large power ion source for NBI. In recent years, RF driven plasma discharge, plasma density control, RF driven plasma diagnostic, RF transformer, initial plasma technology and its technologies are investigated and several prot
otype RF ion sources (prototype) are tested in a test platform in Southwester Institute of Physics (SWIP). RF power of 40KW and 1.2× 1018/m3 have been achieved. In the end of 2013, the second neutral beam injection equipped RF ion sources will be operated. 怪诞家族
