The ultra-cold ion (UCI) source is based on creating very cold ion beams by nearthreshold photo-ionization of a laser-cooled and trapped atomic gas. The UCI source has the potential of producing ion beams with a brightness and current comparable to the liquid-metal ion source (LMIS) [1], which is the current state-of-art for focused ion beam (FIB) technology. We have already shown [2] that the UCI source can provide much lower energy spread than LMIS, and may therefore offer a route toward 1-nm ion beam milling [3].
