摘要

我们最近在模拟模型中加入了占位概率形式主义(OPF)[C. Stehlé 和 S. Jacquemot,Astron. Astrophys.我们利用修订后的模型分析了在大型螺旋装置中氢丸烧蚀云测得的光谱,发现烧蚀云中的电子密度与背景等离子体的电子温度密切相关。这种相关性在本次分析中首次得到了证实,并为磁约束聚变等离子体的颗粒烧蚀模拟研究提供了新的视角。

Better Understanding of Hydrogen Pellet Ablation Cloud Spectra through the Occupation Probability Formalism in LHD
We have recently incorporated the occupation probability formalism (OPF) in the simulation model [C. Stehlé and S. Jacquemot, Astron. Astrophys. 271, 348 (1993)] to have a smooth transition from discrete lines to continuum spectrum in the wavelength range near the Balmer series limit. We have analyzed spectra measured for the hydrogen pellet ablation cloud in the Large Helical Device with the revised model, and have found that the electron density in the ablation cloud has a close correlation with the electron temperature of the background plasma. This type of correlation is first confirmed in the present analysis and should give a new insight in the simulation studies of pellet ablation for the magnetically confined fusion plasma.
