摘要

利用垂直几何Johann光谱仪记录了激光爆炸铝箔和带铝点的聚酯薄膜的k壳发射光谱,具有较高的光谱和空间分辨率。实验使用圆柱形的二维氢码“ATLANT”进行建模。我们描述了我们的新型原子物理后处理器“XEPAP”,它在这里用于合成发射光谱。将模拟结果与实验光谱进行了比较,并推导出发射等离子体的参数。

X-ray emission diagnostics of the densest part of plasma at laser-exploded foils
K-shell emission spectra from laser-exploded aluminum foils and mylar foils with aluminum dots are recorded with a high spectral and spatial resolution using vertical-geometry Johann spectrometer. The experiments are modelled using cylindrical version of two-dimensional hydrocode "ATLANT." We describe our novel atomic physics post-processor "XEPAP" that is used here for the synthesis of the emission spectra. The predictions of the simulations are compared with the experimental spectra and the parameters of the emitting plasmas are deduced.
