Abstract: The fast ion Dα (FIDA) diagnostic in the HL-2A tokamak is introduced in this paper. The fast ion distribution in phase space is obtained by analyzing FIDA spectra with FIDASIM and TRANSP. A theoretical fast ion population calculated by the TRANSP code is input for the FIDASIM code. The collision-radiation model is solved by the FIDASIM code to obtain the theoretical FIDA spectrum. The comparative analysis of experimental and simulation results shows that the simulated FIDA spectrum evolution is consistent with the experimental result, therefore the fast ion distribution calculated by the TRANSP code is verified. 

Key words: Fast ion Dα diagnostic, FIDASIM code, Distribution of fast ions

摘要: 介绍了 HL-2A 装置上的快离子 Dα(FIDA)诊断,并利用 FIDASIM 与 TRANSP 程序对快离子进行模 拟分析,通过分析 FIDA 谱获得了快离子在相空间的分布。对模拟结果与实验结果进行对比,分析表明模拟得到 的 FIDA 谱的演化趋势与实验吻合,验证了用 TRANSP 程序模拟的快离子分布的可靠性。
