我们提出了一种利用脉冲磁透镜将中性原子成像到纳米尺度的方案，并通过数值计算证明了其可行性。该方案实现了几厘米量级的焦距和小于10 nm的焦斑。有了这些结果，就有可能以并行和时间有效的方式在表面上创建亚10 nm结构。当与亚稳态惰性气体原子一起使用时，并与电子光谱学相结合，该方案可以创建一个化学敏感的显微镜，可以在纳米尺度上探测表面。
We present a scheme for imaging of neutral atoms to the nanoscale with a pulsed magnetic lens and show its viability through numerical calculations. This scheme achieves focal lengths on the order of several centimeters and focal spots of less than 10 nm. With these results, it is possible to create sub-10 nm structures on surfaces in a parallel and time-efficient manner. When used with metastable noble gas atoms, and in combination with electron spectroscopy, this scheme can create a chemically sensitive microscope which can probe surfaces on the nanometer scale.
