摘　　要：HL-2A装置激光吹气系统采用了全新自动控制的设计方法,实现了杂质注入量、靶片位移以及激光器被触发的时刻的精确自动控制。运行结果表明,该系统能把杂质的注入量控制在适当的水平,既不对等离子体约束产生影响,又便于光谱测量和杂质粒子输运研究。给出了激光吹气系统的设计,以及初步的实验结果。A new auto-control system of laser blow-off on the HL-2A tokamak has been designed. It can accurately control the quantity of injected impurity, the target displacement and the trigger time. The study indicated that when the quantity of injected impurity was kept in suitable level, injected impurities do not make influence on plasma confinement but give convenience for spectrum measurement and impurity transport research. The design of laser blow-off system and experimental result are presented.
