我们报告的中性原子成像设备，将用于化学敏感的表面显微镜和纳米纤维的进展。我们的新技术，用于提高原子透镜的折射率和校正色差是基于一个基本的范式转变，从连续光束聚焦脉冲，三维的方法。对该系统的模拟表明，它将为实现纳米级真实原子成像的长期目标铺平道路。使用一个原型透镜与亚稳态氖的超音速光束，我们已经成像的复杂图案具有较低的失真和较高的分辨率比以往任何实验中所示。与模拟的比较证实了基本的理论，并鼓励进一步完善的过程。
We report on progress towards a neutral atom imaging device that will be used for chemically sensitive surface microscopy and nanofabrication. Our novel technique for improving refractive power and correcting chromatic aberration in atom lenses is based on a fundamental paradigm shift from continuous-beam focusing to a pulsed, three-dimensional approach. Simulations of this system suggest that it will pave the way toward the long-sought goal of true atom imaging on the nanoscale. Using a prototype lens with a supersonic beam of metastable neon, we have imaged complex patterns with lower distortion and higher resolution than has been shown in any previous experiment. Comparison with simulations corroborates the underlying theory and encourages further refinement of the process.
