Abstract

This work describes the tests performed with a newly built hollow-cathode lamp to ensure its capability to measure atomic parameters such as transition probabilities accurately. We discuss the design of the lamp and the experimental setup that will be used to measure transition probabilities. We show the discharge characteristics of the lamp and also the stability of spectral emission of the lamp over a period of two hours. Finally, it is concluded that the experimental setup, the lamp, and a camera with high resolving power are well suited for the measurement of the transition probabilities of doubly ionised rare-earths like Nd III.

Graphical abstract illustrating the use of a hollow-cathode lamp setup for accurately measuring branching fractions of rare-earth elements. The setup includes a diffraction grating spectrometer and a CMOS camera to detect radiation across a spectral range of 200 nm to 800 nm with a resolving power of 150,000 at 450 nm

精确测量稀土元素支化分数的空心阴极灯的特性。

这项工作介绍了对新制造的空心阴极灯进行的测试，以确保其能够准确测量原子参数，如跃迁概率。我们讨论了灯的设计和用于测量跃迁概率的实验装置。我们展示了灯的放电特性，以及灯在两小时内光谱发射的稳定性。最后，我们得出结论，实验装置、灯管和具有高分辨率的照相机非常适合测量双电离稀土（如钕）的跃迁概率。该装置包括一个衍射光栅光谱仪和一个 CMOS 相机，用于探测 200 纳米到 800 纳米光谱范围内的辐射，450 纳米分辨率为 150,000 分辨率。
