论文摘要
我们证明了通过自支撑箔在传输实验中keV离子的电荷状态，能量和角度分布的同时测量。使用飞行时间方法，我们引入了静电偏转设备，以扩展到现有的中型能量离子散射（MEIS）仪器。在25至250 keV的能量范围内，对最初单一带电的HE，N，O和NE的最初单一带电的光束进行了区分，并量化了不同的正，中性和负电荷态。同时，已经评估了与所有检测到的颗粒相互作用后的离子能量，而颗粒可以通过偏转角度区分。自支撑的薄碳箔被用作样品，以我们的实验在可用的文献数据中进行基准测试。
We demonstrate simultaneous measurements of the charge state, energy and angular distribution of keV ions in transmission experiments through self-supporting foils. Using a time-of-flight approach we have introduced an electrostatic deflection apparatus as an extension to existing medium energy ion scattering (MEIS) instrumentation. Different positive, neutral and negative charge states have been discriminated and quantified for initially singly charged beams of He, N, O and Ne in the energy range from 25 to 250 keV. In parallel, the ion energy after interaction with the target has been assessed for all detected particles, while particles can be discriminated by deflection angle. Self-supporting thin carbon foils were used as samples to benchmark our experiments with literature data where available.
