摘　　要：为满足HL-2M装置高约束模式及高参数实验需求,HL-2M装置规划3条中性束注入(NBI)加热束线,NBI加热功率为15MW。第1和第2条束线是基于正离子源的NBI加热束线,根据中后期高参数实验状态确定第3条束线采用正离子源或者负离子源。本文简要介绍了HL-2M装置的加热束线布局和系统设计概念,综述了基于4套80k V/45A/5s离子源的5MW-NBI中性束加热束线的设计参数及研制进展。在物理和工程可行性简要分析基础上,给出了采用2套200kV/12.5A/10s热阴极负离子源的2.5MW-NBI束线的概念设计、工程设计及技术研究进展。In order to meet the requirements of high confinement mode and high parameter experiment on HL-2 M tokamak, 3 neutral beam injectors(NBI) with total heating power at 15 MW are planned. The 1 st and 2 nd NBI beamlines employ positive ion sources. It will be determined by the parameters in later operation periods of HL-2 M tokamak that whether positive or negative ion sources taken by the 3 st NBI beamline. In this paper, the layout of all NBI beamlines on HL-2 M tokamak and the system design idea are given firstly. Then the designed parameter and development progress of the 5 MW-NBI beam based on 4 sets of 80 kV/45 A/5 s ion sources are reviewed. Based on the brief analysis of the physics and engineering feasibility, the conception design, the engineering design and the technological research progress of a 2.5 MW-NBI beamline, which uses 2 sets of 200 kV/12.5 A/10 s negative hot cathode ion sources, are introduced.
