OMA-Ⅲ对He-MIP的光谱诊断

Spectral Diagnostics of He-MIP Using OMA-Ⅲ

用微波感偶等离子体(MIP)作为原子发射光谱的激发源的可行性和优越性已被大量实验所证实。由于氦具有高的电离电位和高能量、长寿命的亚稳态能级,因而用微波感偶氦等离子体(He-MIP)进行原子发射光谱分析实验有效率高,背景辐射光谱简单。

Emission spectra of a low pressure He-MIP were studied. Spatial distributions of emission spectral intensities, excitation temperatures, mtastable population and electronic number density were obtained.
