New Publication: “Cold electron sources using laser-cooled atoms”
This invited article reviews cold atom electron sources, describing the many different implementations of the concept and an overview of the relevant theory behind their operation. We compare results from recent cold electron diffraction experiments with typical results achieved using conventional thermal sources, highlighting the potential of cold atom sources for single-shot and ultrafast diffraction images of non-crystalline objects.
