| 摘 要： | 实验测量了诊断中性束(DNB)中H0的4种主要能量成分(全能量，半能量，1/3能量，1/18能量)，运用光谱法来分析中性束的束成分所占百分数。根据多普勒效应，中性束中的氢粒子发出的Ha波长偏离本底的Ha波长，波长偏移量与氢粒子的能量相关，从而在光谱仪上得到多峰Ha谱线。通过编写程序并以此对实验的原始谱线进行了初步和精确拟合，最终准确有效地分析出中性束的束成分和束能量。实验测得DNB束流的中性氢粒子的全能量、半能量、1/3能量和1/18能量4种成分分别占15%,42%,35%,8%。

| Abstract: | An optical spectroscopy based on Doppler shift is applied to measuring energy and the percentages of the four energy component—the full energy, half energy, third energy and the eighteenth energy of diagnostic neutral beam(DNB) on HT-7 Tokamak. According to the Doppler effect, the multi-peak Ha spectra is obtained, which are emitted by the neutral beam and separated from the unshifted Ha. Both the measurement principle and the data processing algorithm are presented in this paper. The experimental results of DNB show the percentages of the four energy component are 15%, 42%, 35% and 8% respectively. |
