摘　　要：超声分子束注入在中国环流器一号和新一号装置首次采用。与常规送气相比，由于气体 粒子注入深化，形成电子密度的峰化和密度极限的提高，并导致约束的改善。欧姆加热等离子 体的能量约束时间的线性范围增长到　　。实验结果表明，超声分子束注入是一种 先进而简单的气体加料方法。Supersonic molecular beam injection (MBI), a new fuelling method, has been used in the HL-1 and HL-1M tokamak for the first time.Compared with the conventional fuelling, MBI has the following advantages:the fuelling particles can penetrate deeper and a peak in electron density distribution is formed which improves the confinement. The upper end of density ne for the linear ohmic confinement regime can reach 4 10`19gm-3. The experimental results indicate that MBI is an advanced and simple gas fuelling method for fusion plasma.
