论文摘要
我们提出了在3D离子传输实验中可视化对比度图的选项。通过自支撑，单晶硅箔传输的离子的角度分布和飞行时间的同时测量可以映射强度和不同的能量损失矩。主要使用具有入射能50和200 keV的He离子和质子的脉冲梁和质子的脉冲梁和质子的脉冲梁检测到传输的弹丸。相反的差异是在改变弹丸类型和能量时观察到的差异，这可以归因于样品核和电子结构，并证明了影响参数依赖性能量损失过程。我们的结果为解释前瞻性传播研究中获得的数据提供了基础，例如使用氦离子显微镜。
We present options for visualizing contrast maps in 3D ion transmission experiments. Simultaneous measurement of angular distributions and flight time of ions transmitted through self-supporting, single-crystalline silicon foils allows for mapping of intensity and different energy loss moments. The transmitted projectiles were detected mainly for random beam-sample orientation using pulsed beams of He ions and protons with incident energies 50 and 200 keV. Differences in contrast, observed when varying the projectile type and energy, can be attributed to sample nuclear and electronic structure and bear witness to impact parameter dependent energy loss processes. Our results provide a base for interpretation of data obtained in prospective transmission studies when for example using a helium ion microscope.
