This project will develop atomic-scale imaging that is able to bypass the resolution limitations of modern electron microscopes. The project will investigate the physical processes underlying a new imaging source based on extracting cold electrons from laser-cooled atoms. Ultrashort pulses of cold electrons will enable time-lapse imaging of fundamental processes at the nano-scale, with applications in fundamental biosciences and materials science.

该项目将开发能够绕过现代电子显微镜分辨率限制的原子级成像。该项目将研究基于从激光冷却原子中提取冷电子的新成像源的物理过程。冷电子的超短脉冲将能够在纳米尺度上对基本过程进行延时成像，并应用于基础生物科学和材料科学。
