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.

同时评估与超薄自支撑目标相互作用的中等能量离子的能量、电荷状态和角度分布：飞行时间方法

我们展示了通过自支撑箔在传输实验中同时测量 keV 离子的电荷状态、能量和角度分布。我们使用飞行时间方法引入了静电偏转装置，作为对现有中等能量离子散射 (MEIS) 仪器的扩展。对于能量范围为 25 至 250 keV 的 He、N、O 和 Ne 的初始单电荷束，不同的正、中性和负电荷状态已被区分和量化。同时，对所有检测到的粒子评估了与目标相互作用后的离子能量，而粒子可以通过偏转角进行区分。自支撑薄碳箔用作样品，以在可用的情况下使用文献数据对我们的实验进行基准测试。
