超声分子束在HL-1M托卡马克等离子体中的消融和穿透

Penetration and attenuation of SMB fueling in tokamak plasma

讨论并研究了超声分子束在托卡马克等离子体中的消融和穿透问题 ,其中包括了分子束的绝热膨胀 ,团簇的形成和解离 ,束的静电屏蔽效应和冷通道效应 .研究结果表明 ,在考虑了这些效应以后数值得到的结果与实验结果相近 .

In this paper, a discussion and an optimizing numerical analysis of the penetrat ion and attenuation of the thermonuclear tokamak plasma fueling by the supersoni c cluster molecular beam(SMB) has been presented.The cluster formation and disso lution,SMB adiabatic expansion,shielding and cooling effect are all taken into a ccount.An optimized numerical model is applied in the analysis and shown to be i n good agreement with the experimental observations.The possibility for fueling large tokamak plasmas with SMB injection is explored.
