This research applies experimental measurements and NUBEAM, ONETWO and TRANSP modules to investigate the shine-through (ST) loss ratio and beam heating percentage of neutral beam injection on EAST. Measurements and simulations confirm that the ST loss ratio increases linearly with beam energy, and decreases exponentially with plasma density. Moreover, using the multi-step fitting method, we present analytical quantitative expressions of ST loss ratio and beam heating percentage, which are valuable for the high parameter long-pulse experiments of EAST.

EAST上中性射束注入引起的透射损耗和射束加热的数值和实验评估

本研究应用实验测量和 NUBEAM、ONETWO 和 TRANSP 模块来研究 EAST 上中性光束注入的透光 (ST) 损耗比和光束加热百分比。测量和模拟证实，ST 损耗比随光束能量线性增加，并随等离子体密度呈指数下降。此外，利用多步拟合方法，我们给出了ST损耗比和束流加热百分比的解析定量表达式，这对于EAST的高参数长脉冲实验具有重要意义。
