摘要
采用20 μm的狭缝配平面晶体谱仪构成空间分辨光谱测量系统,对Al激光等离子体的K壳层发射谱进行测量.利用Al的Ly-α线谱的翼部Stark展宽效应推得电子密度空间分布轮廓,建立了翼部Stark展宽法测量高密度等离子体电子密度的诊断技术.
Abstract
The K-shell emission lines of laser-produced aluminum plasma were measured by the space-resolved spectrometer, which was constructed by a flat crystal spectrometer with a 20 μm-wide slit. The electron density profile beyond the critical density is obtained by fitting the Stark-broadened line wings of hydrogenic ions, then the diagnostics on high electron density has been developed tentatively.
