摘要
主要介绍HL 1M托卡马克装置三种加料方式所得的密度特性结果。用弹丸注入 (PI) ,超声分子束注入 (SMBI)和常规脉冲送气 (GP)获得等离子体电子密度Ne分别为 5 3× 10 19m 3,8× 10 19m- 3和 7× 10 19m- 3。前者获得的能量约束时间τe却比后者高 30 %以上。比较了不同再循环条件下各种加料实验的结果 ,由密度演变、H信号和软X射线 (SX)信号的时空变化显示三种加料方式粒子沉积区域不同。进一步分析表明
The main experimental results with three type of fueling method used on HL 1M tokamak plasma have been presented. The plasma electron densities Ne of 5.3×10 19 m -3 , 8.0×10 19 m -3 and 7.0×10 19 m -3 were obtained by Pellet Injection (PI) Molecular Beam Injection (MBI) and Gas puffing (GP) respectively. The energy confinement time e of 26ms obtained by PI is greater than 30% compared to GP fueling discharges which is created by different penetration depth of the refueling particles.
