Compact robust testbed for cold-atom clock and sensor applications

Our goal in this Phase II effort is to construct and test a compact, robust testbed for generating laser-cooled strontium atoms on a mobile platform. The focus of the Phase I effort was designing and fabricating an ovenized strontium source that also serves as a 2D+ MOT cell. In Phase II, we will integrate the strontium source into an all-glass-and-silicon vacuum system maintained by a miniature ion pump. This effort will reduce SWaP and significantly reduce the amount of metal, including ferrous materials, in the system. The vacuum cell will be integrated into a turnkey with modular components that allow for easy interchangeability of functions such as timekeeping, sensing, and navigation.
